Full textAbstract:
In this thesis, the ten stocks with the highest dividend yield from the OMXS30 have been used to construct a portfolio, a strategy called The Dogs of the Dow. The portfolio was equally weighted and rebalanced every year. The purpose of this thesis is to see how the strategy would perform in terms of return and risk compared to the market. To define the market two indexes were used, OMXSPI and OMXSGI, which excludes and includes dividends respectively. A low dividends portfolio was also used as a benchmark. Though beating the market some individual years and showing a tendency of performing better in an up-going market, the strategy's average annual return of 9.69 percent for the whole period only beat one of the benchmarks. The strategy's risk was fairly similar to the market risk hence, it does not compensate the lower return with lower risk. The Sharpe ratio showed that the Dogs of the Dow portfolio had the best risk adjusted return in only two out of the eleven years. This points towards the conclusion that the strategy would not have performed better, overall, compared to the benchmarks between the years of 2005 and 2015.

Full textAbstract:
This paper investigates whether the Dogs of the Dow (or “Dow Dogs”) investment strategy is applicable to the Swedish stock market during the period 1996-2015. The strategy uses dividend yield as a way to identify undervalued stocks. Likely explanations to the strategy’s performance are contrasted between the Overreaction Hypothesis from the field of behavioral finance and the Efficient Market Hypothesis (EMH) from financial economics. The paper follows the original method formed by John Slatter, but is however extended by adding adjustments for risk, transaction costs and taxes to reflect a more realistic market setting. Our empirical findings suggest that the Dow Dogs strategy barely beats the market by 0.02 Sharpe ratio unit points. The strategy’s performance may be rather unimpressive, but it is interesting to acknowledge that the portfolio performed best during the market’s worst downturns. To conclude, our results lack statistical significance and we cannot reject the null hypothesis of no abnormal returns.

Full textAbstract:
BAKGRUND: Investerare har försökt slå marknaden så länge kapitalmarknader har funnits. En investeringsstrategi som använts är ”Dogs of the Dow”. Investeringsstrategin bygger på att investera i de bolagen med högst utdelningsandel. Vedertagna ekonomiska teorier förespråkar även att investeringar i stabila utdelningsbolag ger möjlighet att generera riskjusterad överavkastning. Det finns idag motstridiga bevis från olika aktiemarknader huruvida det går att skapa riskjusterad överavkastning genom placeringar i högutdelande bolag. SYFTE: Syftet med studien är att undersöka om det går att skapa högre riskjusterad avkastning än SIX Return Index (.SIXRX) genom att placera i de aktierna med högst direktavkastning på Stockholmsbörsen. Vidare syftar studien att undersöka både huruvida ”Dogs of the Dow”- strategin och en investeringsstrategi i stabila utdelningsbolag kan generera riskjusterad överavkastning jämfört med index på Stockholmsbörsen. GENOMFÖRANDE: Det skapas två portföljstrategier där den ena utgår från ”Dogs of the Dow” och den andra utgår från placeringar i stabila utdelningsaktier. Studien är en kvantitativ undersökning där data samlas in från välrenommerade databaser. Portföljerna innehåller tio bolag som rebalanseras varje år för att sedan justeras för risk och transaktionskostnader. SLUTSATS: Studien presenterar inga bevis för att det går att skapa riskjusterad överavkastning med utgångspunkt i ”Dogs of the Dow”-strategin på Stockholmsbörsen. Däremot visar studien att det med hjälp av placeringar i stabila utdelningsbolag går att skapa riskjusterad överavkastning på Stockholmsbörsen men utan statistiskt signifikans.BACKGROUND: Investors have been trying to beat the market for as long as capital markets have existed. An investment strategy used to outperform the market is “Dogs of the Dow”. The investment strategy is based on investing in the companies with the highest dividend yield. Economic theories argue that investments in companies with stable dividend payouts are able to create risk-adjusted excess returns. There are contradictory evidence from different markets whether it is possible to earn risk-adjusted excess return through high-yield investments. PURPOSE: The purpose of the study is to investigate whether it is possible to earn higher risk- adjusted returns than the SIX Return Index (.SIXRX) through investing in the highest dividend yield companies on the Stockholm Stock Exchange. The study aims to investigate whether the “Dogs of the Dow” strategy and an investment strategy in companies with stable dividend payouts can generate risk-adjusted excess return compared to the SIX Return Index. COMPLETION: There are two portfolio strategies, one of which is based on ”Dogs of the Dow” and the other is based on investments in companies with stable dividend payouts. The quantitative study collects data from reputable databases. The portfolios contain ten companies that are rebalanced each year and the returns are adjusted for risk and transaction costs. CONCLUSION: The study presents no evidence that it is possible to earn risk-adjusted excess return with the “Dogs of the Dow” strategy on the Stockholm Stock Exchange. However, the study shows that investments in companies with stable dividend payouts can earn risk-adjusted excess return on the Stockholm Stock Exchange but without statistical significance.

Full textAbstract:
The current study investigated concept formation in domestic dogs, specifically that of a toy concept. The dog's differential responding (retrieval vs. non-retrieval) to two sets of stimuli suggested a toy concept. Differential responding occurred from the very first trial, indicating that the concept had been formed in the natural environment, not during the experiment. It was hypothesized that a common response may be responsible for the emergence of the class in the natural environment. The results demonstrated that it was possible to expand the class by adding previously non-retrieved objects to the toy class through a common response. It was also shown that the toy concept passed the more stringent criterion (transfer of function test) required validating it as a concept.

The goal of this study is to analyze the performance of the Dogs of Dow (DoD) investment strategy in Latin American stock markets from 1995 to 2011 and also determine if the performance varies on growth and recession periods. The following countries were analyzed: Argentina, Brazil, Chile, Colombia, Mexico and Peru. Our findings suggest that the DoD outperforms the market, on an absolute and on a risk-adjusted basis, in all Latin American countries except Mexico. The results are significant in both statistical and economic terms. In general, the performance of DoD in different sub-periods is in line with the overall period, indicating that the DoD has a superior performance in both growth and recession periods.

Problemformulering: Går det att uppnå en signifikant återkommande överavkastning samt riskjusterad överavkastning i förhållande till den svenska aktiemarknaden genom systematiskt följande av investeringsstrategin “Dogs of the Dow”? Syfte: Syftet är att undersöka huruvida teorin ”Dogs of the Dow” är applicerbar på den svenska aktiemarknaden i sökandet efter en signifikant återkommande överavkastning i förhållande till marknaden. Med detta hoppas det finnas en positiv differens av den riskjusterade överavkastningen gentemot index. Metod: Studien samlar in primärdata för empirin via SIX Trust, SIX Edge samt från Riksbankens hemsida. Sekundärdata härstammar från vetenskapliga artiklar uthämtade från främst JStor och EBSCO Host. Även studentlitteratur, tidigare studier utgör sekundärdata. Studien tillämpar befintliga teorier för att via modeller studera studiens syfte. Resultat: Resultatet anses av författarna vara imponerande. Portföljerna sammansatta i enlighet med investeringsstrategin ”Dogs of the Dow” presterar till de skådade faktorerna i genomsnitt över lag bättre än jämförelseindexen SIXRX och SIX30RX. Resultaten kan dock inte fastställas statistiskt men författarna önskar skilja på statistisk och praktisk signifikans då en möjlig kumulativ effekt genererar enorm förmögenhetsutveckling.Problem: Is it possible to receive a reoccurring significant abnormal return as well as risk adjusted abnormal return against the Swedish stock market through systematic appliance of the investment strategy ”Dogs of the Dow”? Objective: The objective is to study whether the theory ”Dogs of the Dow” is applicable on the Swedish stock market in the search of a significant reoccurring abnormal return against the market. The hopes are to find a positive difference between the risk adjusted abnormal return and index. Method: The study collects the primary empirical data through SIX Trust, SIX Edge as well as from the Swedish central bank. The secondary data is derived from scientific articles, student literature, and previous studies. Models are used to study the objective. Results: The authors find the results to be impressive. The portfolios structured through the investment strategy “Dogs of the Dow” outperform the comparison indices SIXRX and SIX30RX in general on all the observed accounts. The results can although not be stated as statistically significant within any reasonable confidence levels, but the authors would like to emphasize the difference between the terms statistically and practically significant. This since cumulative gains could contribute to a massive gain of wealth which could be practically significant for the long-term investor.

Full textAbstract:
There are increasing concerns that some pedigree breeding practices compromise canine welfare; with many breeds affected by inherited disorders likely due to adherence to breed standards that encourage exaggerated conformations. Consequently, calls for quantitative limits to be included in breed standards have been advocated to safeguard against conformations that are detrimental to canine welfare. This thesis explores the relationships between extreme conformation and disease-risk, to identify the most at-risk conformations currently being selected for, and recommend healthy 'limits'. Three conformation-related disorders of high welfare importance were investigated; brachycephalic obstructive airway syndrome (BOAS), intervertebral disc extrusion (IVDE) and corneal ulceration. Seven hundred dogs entering the RVe's small animal referral hospital were recruited over 14-months; their conformations quantified using established protocols and disease-status assessed. Generalised linear mixed-model analyses demonstrated for the first time that: (1) relatively shorter muzzles and relatively thicker necks increased the risk of BOAS; (2) relatively longer backs, miniaturisation and being overweight increased the risk of IVDE; and (3) the presence of nasal folds, relatively short muzzles, relatively larger eyelid openings and the presence of exposed sclera increased the risk of corneal ulcers. To test the risk estimates generated from this population, a second study of BOAS was carried out in a non-referral population. Short muzzles and thick necks were confirmed to be risk factors for BOAS, with two further lifestyle risk factors identified: obesity and neutering. A questionnaire-based study discovered an owner-perception of BOAS being 'normal for the breed' that may hamper efforts to reduce its prevalence in the future. As such, educational interventions to change attitudes may be required. The results of these studies are hoped to instigate and inform future breed standard revisions, and influence those within the breeding community to change current breeding practices to improve canine welfare by selecting for more moderate, lower-risk morphologies.

Full textAbstract:
Separation anxiety is one of the most common behavioral disorder in companion dogs. Dogs not suffering from separation anxiety may still exhibit separation-related behaviors, which can differ depending on environmental contexts. In the present study, dogs without separation-related problems were video recorded during a short separation (3 min) from, and during reunion with, their owner. Comparison was done between if the dogs had played or been calm pre-separation. The dogs spent most time in proximity to the entrance and gazing towards where the owner left during separation. Their body-position was mostly standing, followed by sitting. All dogs were wining during separation, which occurred approximately four times more than barking. Dogs that had played pre-separation were running around more and had a longer latency to the first movement, compared to when they had been calm pre-separation. During reunion, when dogs had played pre-separation, they wagged their tail more and had a longer latency to lip licking, compared to when they had been calm pre-separation. The separation behaviors that occurred in this study aligns with previous work in this subject. Furthermore, one can suggest that play pre-separation might have an effect on separation behaviors, where speculations can be done if the positive affect associated with play might be the underlying cause for these findings.

Full textAbstract:
Cortisol is a stress hormone which is released from the adrenals in the Hypothalamic-Pituitary-Adrenal (HPA) axis and plays a major role in animal stress response. Cortisol is used as a stress marker and can be sampled using different methods. A good non-invasive method and a good measure of chronic stress is to measure cortisol through hair. Cortisol is stored in hair for months and therefore reflects chronic stress. The aim of this study was to investigate if cortisol concentration differs depending on coat color. Hair samples from 20 black and white Border collie dogs was analysed and used in this study. Cortisol was extracted with methanol and analysed with ELISA. The results showed no significant difference between black and white coat color within the population while there were individual differences. The results also showed that the sexes do not affect the cortisol concentration. In summary, coat color (black and white) has an effect on cortisol concentration which means that the factor color does need to be taken into account when measuring cortisol through hair.

Canine thunderstorm phobia is a common, frustrating, and complex problem that, due to the often severe nature of the clinical signs, can lead to canine relinquishment to shelters. Although a potentially treatable disorder, existing treatment options have several limitations and variable success rates. Three survey-based studies were conducted to increase the knowledge base for canine thunderstorm phobia. The first study distributed 1445 surveys through 16 Kansas veterinary clinics to determine the prevalence and characteristics of thunderstorm phobic dogs and assess differences between affected and non-affected dogs. Of 463 dogs surveyed, 240 were thunderstorm phobic as assessed by their owners. Severe weather warning systems may play a role in thunderstorm phobia. Thunderstorm phobic dogs were more fearful when exposed to tornado sirens, both during actual storms and siren testing, indicating a possible effect of classical conditioning. No differences were noted regarding sex, breed, pedigree, or neuter status. Most affected dogs preferred to be indoors remaining near their owners. The second study distributed 1600 surveys through eight Kansas animal shelters to determine the prevalence of relinquished dogs with thunderstorm phobia. Other reasons for relinquishment were also assessed. A fear of thunder was among the least common behavioral problems leading to relinquishment in dogs. Only a quarter of owners had visited a veterinarian for assistance with behavioral problems. The third study involved the administration of dog appeasing pheromone (DAP) in a double-blind, placebo-controlled, randomized clinical trial to assess its efficacy as a sole treatment for thunderstorm phobia. Data was collected from 60 dog owners using behavioral assessment questionnaires. In dogs given the placebo, six behaviors significantly improved, with another eleven showing a numerical trend toward improvement. However, in dogs given DAP, significant improvement was seen in three of these same behaviors. Consequently, these results do not indicate the potential use of DAP for reducing fearful behaviors associated with thunderstorm phobia when compared to negative controls. Information gained from these studies allows veterinarians and behavioral researchers to better understand the extent of this behavioral disorder and hopefully stimulates future research to find new and more effective ways to treat it.

Full textAbstract:
Dogs have lived with us for thousands of years, so we have learned to understand one another. Dogs have been shown to synchronize their behavior with humans. Behavioral synchronization is characterizes by doing the same thing at the same time and in the same place as someone else. This synchronization is often dependent on the relationship and the emotional state of the individuals. The main aim in this study was to develop a method to test behavioral synchronization and also to investigate how this, but also other behaviors, are effect by preceding human-dog interactions. Privately owned dogs (N=21) were tested with three different treatments (play, pet or ignore). The test procedure consisted of the owner walking or standing still in a predefined pattern, while their dog was freely roaming. This study showed that dogs adapted their movement pattern to their owners. This was similar to previous studies showing that the method developed can be used to test behavioral synchronization between owner and dog. Dogs explored the test arena less after play interaction and they also tended to seek more eye contact with their owners, but the interactions did not affect how much time spent in human proximity, how much they followed them or on dogs movement pattern.

Full textAbstract:
Att investera sina pengar i aktier är ett populärt val bland finansiella instrument för framtida avkastning. En målsättning hos flera investerare är att överträffa sin portföljs jämförelseindex till en så låg risk som möjligt. För privatpersoner med mindre kunskap och tid kan en mer simpel investeringsstrategi vara lösningen. Investeringsstrategin ”Dogs of the Dow” syftar till att köpa de tio aktier med högst direktavkastning och hålla dem under ett år innan omstrukturering. För att göra strategin mer användbar för privatpersoner med olika målsättningar för sitt sparande och placerande har den ursprungliga versionen av ”Dogs of the Dow” modifierats i denna studie. Studien undersöker strategins förmåga att generera överavkastning med varierande storlek på portföljer samt en längre hållningsperiod. Portföljerna har bestått av 15,10 och 5 aktier samt hållningsperioder på ett och fem år. Frågeställningen formulerades på följande sätt: Kan den investeringsstrategi som tagits fram överträffa jämförelseindex OMXSBGI? Är strategin bättre på kort eller lång sikt och kan överavkastning uppnås efter riskjustering? Resultatet av studien har analyserats och diskuterats utifrån den teoretiska referensramen. Detta är en kvantitativ studie där aktier från Nasdaq OMX Stockholm Small, Mid och Large Cap har ingått. Aktieportföljerna har riskjusterats med Sharpe och Treynorkvoten och överavkastning har analyserats utifrån t-test. Syftet med de statistiska testen är att se ifall den riskjusterade överavkastningen är signifikant skild från noll. Utifrån de statistiska tester som utförts är det 4 av 12 portföljer som uppvisar en statistisk signifikans. Samtliga portföljer som uppvisade en statistisk signifikans hade en hållningsperiod på fem år. Därmed kan slutsatsen dras utifrån observationerna att det finns ett statistiskt stöd för investeringsstrategin med en längre hållningsperiod och att den genererar en överavkastning gentemot sitt jämförelseindex.

Full textAbstract:
The central aim of this thesis is to critically examine the values associated with dogs in Victorian British art and visual culture. It studies the redefining and restructuring of the domestic dog as it was conceptualized in visual culture and the art market. It proposes that the dog was strongly associated with social values and moral debates which often occurred within a visual arena, including exhibitions, illustrated newspapers, and prints. Consequently, visual representations of the dog can be seen as an important means through which to study Victorian culture and society. Historians have agreed that the Victorian period was a significant turning point for how we perceive the dog. Harriet Ritvo, Michael Worboys and Neil Pemberton cite the Victorian period as founding or popularizing many recognisable canine constructs; such as competitive breeding; a widespread acceptance of dogs as pets; and the association of particular breeds with particular classes of people. Phillip Howell defines the Victorian period as the point at which the domestic dog was conceptually established. The figurative domestic dog did not simply exist in the home but was part of the home; an embodiment of its core (often middle class) values. As such, the domestic dog became the standard by which all other dogs were perceived and the focal point for related social debates. Yet most studies concerning the Victorian dog overlook the contribution of visual culture to these cultural developments. William Secord compiled an extensive catalogue of Victorian dog artwork and Diana Donald examined Landseer and the dog as an artistic model yet neither have fully situated the dog within a broader Victorian social environment, nor was their intention to critically examine the dog’s signification within the larger visual landscape. Chapter One provides this overview, while subsequent chapters provide studies of key canine motifs and the manner in which they operated in art and visual culture. Underpinning this thesis is a concern with the Victorian moral values and ideals of domesticity in urban environments. These values and their relation to the dog are explored through the framework of the social history of art. Seen through this methodology, this thesis allows the relationship between canine debates, social concerns, and visual representations to be understood. It will argue that the figure of the dog had a significant role to play both socially and visually within Victorian society and propose a reappraisal of the dog in art historical study.

Full textAbstract:
Of the approximately 3.9 million dogs that enter US animal shelters each year, many exhibit behaviors related to fear, which can affect their likelihood of adoption. Current dog training procedures to treat fear include counterconditioning and desensitization, which can often take months or years to show any behavior change and do not teach specific behaviors aimed to increase the dog's chance of being adopted. The current study used a negative reinforcement shaping procedure to teach fearful dogs to approach and and interact with people. The results showed that constructional fear treatment increased the amount of time the dog spent at the front of the kennel, and increased sniffing, tail wagging, and accepting petting for all 3 participants.

Morters, Michelle. "Improving rabies control in free-roaming dogs." Thesis, University of Cambridge, 2014. https://www.repository.cam.ac.uk/handle/1810/252882.
Full textAbstract:
Canine-mediated rabies is a serious zoonosis responsible for at least 55,000 human deaths every year, primarily in less developed communities in Asia and Africa where domestic dogs are free-roaming. The disease can be effectively controlled through vaccinating at least 45% of the dogs in a population; however the impact of vaccinations on disease incidence may be affected by dynamic demographic and immunological processes. Specifically, the contribution of these processes, and their regulatory factors, to vaccination coverage and rabies transmission has not been comprehensively estimated. To improve rabies control, through field interventions and epidemiological modelling, more information regarding the effect of these processes, and their regulatory factors, on population and disease dynamics and vaccinal responses was needed. This required a multifaceted approach, using techniques from the fields of population ecology, vaccine-immunology, social science and epidemiological modelling. Demographic data were collected from four populations of free-roaming domestic dogs, two in South Africa and two in Indonesia where rabies is endemic. Longitudinal, individual-level data were obtained by direct observation and surveys, and community-level data by participatory methods. Longitudinal, serological data were collected from three cohorts within the populations. Epidemiological models were based on epidemic theory and empirical data from this current study and previous studies. A wide array of data were generated relevant to planning rabies control programmes, however of particular importance was evidence regarding positive and negative the impacts of human factors on population and disease dynamics. Nearly all of the dogs were owned, despite being free-roaming, and were accessible for vaccination through their owners; and population size was regulated through human demand for dogs and a substantial fraction of dogs was acquired from outside the communities. These translocated dogs may contribute to the spread of rabies, necessitating widespread and sustained vaccination programmes. Considerable differences in the handleability of dogs between locations and, thus ease of vaccine delivery, may also be attributable to differences in human-dog interactions. Finally, a critical review of the literature, and evaluation of epidemiological models, suggests that human interference in the transmission processes may reduce the incidence of rabies and vaccination threshold. This study has provided specific evidence that human behaviours are likely to be critically important in relation to the transmission and control of canine-mediated rabies ? and is the first to properly identify this. Further detailed studies are required to explore these behaviours and how they vary culturally and geographically. In addition, the results highlight the critical role that demographic processes more generally, as well as immunological decay, play in influencing the long term success of rabies vaccination programmes. Overall, this research has provided valuable support for planning rabies control programmes and for parameterisation of epidemiological models of infectious diseases, including rabies.

Full textAbstract:
The aim of this study was to investigate if the dog’s behaviour and the interactions between the dog and the owner differ depending on lifestyle, breed or sex of the dog. For this we employed the Strange Situation Procedure, a test inspired from Mary Ainsworth´s study, which investigated the attachment of human infants to their mothers. There were two breeds, Border collie and Shetland sheepdog and a total of 58 dogs that participated in this study. The two breeds were divided into two lifestyles, competition dogs and pet dogs. A PCA was used to find correlations between the behavioural variables and the factors were then analysed in a Mann Whitney U test to test the differences between breed, sex and lifestyle. In this study no differences in behaviour between the two lifestyles were shown. However, the results showed that there were some differences between the two breeds and between the two sexes in behavioural expressions. The differences between the breeds were quite expected because there are many different breeds today which are selected for various morphology and behavioural traits which could influence their behaviour. The difference in behaviour between the two sexes can be because of evolutionary heredity. Further studies on this subject should have bigger and more even sample size, longer separation time, a more balanced gender distribution of the owners and to also analyze the cortisol levels.

Full textAbstract:
Each year in the UK, in addition to the stray dogs passed onto animal welfare organisations and dog kennels from the dog warden service, many others are handed over by members of the public for rehoming. Dogs Trust rehomed over 12,000 dogs during 2006. The stresses of staying in kennels and the change in environment can have a negative impact on the health of these dogs and this compromises their welfare and affects the success of rehoming. There have been very few studies examining the processes influencing success of rehoming in the UK. The current studies were conducted to describe indirect effects such as the previous owners, the dogs and their home environments, the health of the dogs in kennels and the effect factors directly affecting the success of rehoming these dogs. A descriptive study showed the most common reasons for dogs to be relinquished were behavioural problems and the owner feeling that the dog needs more attention than they can give it. Additionally, it was shown that behavioural issues were more common amongst those dogs relinquished for the second time whilst owner-related factors were more common for those dogs relinquished for the first time. Another descriptive study focussing on the, health of the dogs whilst in kennels showed that many dogs were ill when they arrived at the kennels making it difficult to prevent the introduction of diseases. It was also found that if the dogs were ill soon after adoption they were more likely to be rehomed unsuccessfully and returned to kennels. Risk factors that increased the likelihood of a dog being rehomed unsuccessfully were identified using a prospective cohort study. The results suggest that behavioural problems are an important factor especially if the dog had shown aggressipn towards people. However, there were also indications that by the owners obtaining advice, this risk couid be significantly reduced. Attending training classes significantly decreased the chance that the adoption would be unsuccessful. The data a1so suggested that families with younger adults and young children, and owners who found that the effort and work involved in looking after their dog to be more than they expected were more likely to return the dog. This study highlighted the importance of behavioural problems and therefore the agreement between members of staff at the rehoming kennels during the behavioural assessment of dogs was assessed using an additional study. These studies were able to highlight particular factors which could be changed or where new policies could be implemented in order to prevent some relinquishments or improve the reterition of dogs post-adoption.

OBJECTIVE: The purpose of the study reported here was to evaluate pharmacokinetics of cefazolin in dogs receiving a single IV injection of cefazolin (22 mg/kg) and dogs receiving simultaneous IV and IM injections of cefazolin (total dose, 44 mg/kg). METHODS: Twelve purpose-bred Beagles (6/group) were assigned to receive a single injection of cefazolin (22 mg/kg, IV) or simultaneous injections (22 mg/kg, IV, and 22 mg/kg, IM). Interstitial fluid was collected over a 5-hour period using ultrafiltration probes for pharmacokinetic analysis. RESULTS: Mean cefazolin concentration in the interstitial fluid at 1, 1.5, 2, 3, 4, and 5 hours after injection was 39.6, 29.1, 21.1, 10.3, 6.4, and 2.7 μg/mL, respectively, for the IV group and 38.3, 53.3, 46.4, 31.7, 19.1, and 8.9 μg/mL, respectively, for the IV + IM group. The mean area under the concentration-time curve extrapolated to infinity, maximum concentration, half life and time to the maximum concentration was 74.99 and 154.16 h•μg/mL, 37.3 and 51.5 μg/mL, 0.96 and 1.11 hours, 1.28 and 1.65 hours, respectively, for the IV and IV + IM groups. CONCLUSIONS AND CLINICAL RELEVANCE: Cefazolin concentrations in interstitial fluid of dogs were maintained at > 4 μg/mL for 4 hours after a single IV injection and for 5 hours after simultaneous IV and IM injections. Based on these results, simultaneous administration of cefazolin IV + IM 30 to 60 minutes before surgery should provide interstitial fluid concentrations effective against the most common commensal organisms (Staphylococcus spp and Streptococcus spp) on the skin of dogs for surgical procedures lasting ≤ 4 hours.

Full textAbstract:
Aggressive behavior in dogs poses public health and animal welfare concerns, however the biological mechanisms regulating dog aggression are not well understood. We investigated the relationships between endogenous plasma oxytocin (OT) and vasopressin (AVP)-neuropeptides that have been linked to affiliative and aggressive behavior in other mammalian species-and aggression in domestic dogs. We first validated enzyme-linked immunosorbent assays (ELISAs) for the measurement of free (unbound) and total (free + bound) OT and AVP in dog plasma. In Experiment 1 we evaluated behavioral and neuroendocrine differences between a population of pet dogs with a history of chronic aggression toward conspecifics and a matched control group. Dogs with a history of aggression exhibited more aggressive behavior during simulated encounters with conspecifics, and had lower free, but higher total plasma AVP than matched controls, but there were no group differences for OT. In Experiment 2 we compared OT and AVP concentrations between pet dogs and a population of assistance dogs that have been bred for affiliative and non-aggressive temperaments, and investigated neuroendocrine predictors of individual differences in social behavior within the assistance dog population. Compared to pet dogs, assistance dogs had higher free and total OT, but there were no differences in either measure for AVP. Within the assistance dog population, dogs who behaved more aggressively toward a threatening stranger had higher total AVP than dogs who did not. Collectively these data suggest that endogenous OT and AVP may play critical roles in shaping dog social behavior, including aspects of both affiliation and aggression.

Full textAbstract:
During domestication, the dog( Canis familiaris), have become skilful in understanding human communication and also in communicating with humans. The wolf ( Canis lupus), is not as skilled with this interspecific communication. When dogs are faced with an unsolvable problem, they seek help from human by e.g. gazing at them. This behaviour has been studied and both age and breed group differences have been showed. In this study, we presented dogs with a task that consisted of a solvable and unsolvable problem in order to see if they gazed at their owner and/or an unfamiliar person for help. Although we did not find any difference in breed groups regarding gazing at humans, we did find that adult dogs (dogs older than 2 years) gazed more frequently at their owner and for a longer duration than adolescent dogs (6 months to 2 years). This may be because the adult dogs have more experience of this communication with humans, as they have lived longer with them. These findings empathize the bond between a dog and its owner that seems to grow stronger during the dogs’ life.

Palatability of pet food is an important factor influencing food purchase decision of pet owners. In industry, single- or two-bowl methods are traditionally used to determine food acceptance or preference by pets but shortcomings exist to these methods. The first objective of this study was to propose and develop a preference ranking procedure. Preliminary testing consisted of five phases each lasting five days. Each day twelve beagles were presented 5 treats encased in identical rubber toys (“kongs”). The order of selection was considered as the ranking of preference. The five phases consisted of training, testing lab-baked treats formulations with five varieties of fats, starches and proteins, and commercial foods. The dogs generally ranked 1-2 flavors above others, indicating this procedure could be a more efficient method to determine preference since more samples can be evaluated simultaneously. The second objective was to validate this procedure by following the same process as the preliminary test. The results from phases 2 to 4 showed a similar pattern. For phase 5, various treat formulations were tested by combining the most to least preferred ingredients in each category. The results proved that the ranking of the formulations resembled the preference of the dogs for individual ingredients. Therefore, this procedure was concluded to be reliable. The third objective was to use descriptive sensory analysis to study the sensory characteristics of the treats and gain insights on the drivers of dogs’ preference. Five highly trained panelists profiled the aroma of the treats and the data was analyzed with the preference results collected from the dogs. The external preference maps showed that fish and meaty aromatics tended to be liked by the dogs and grain and musty/dusty aromatics appeared to be disliked. The last objective of this study was to further explore the applications of this procedure by studying the effect of toy/puzzle toy of the treat and ingredient dosage/ratio. With the same dogs, Styrofoam cups (puzzle toy alternative) and kongs were evaluated separately with the same treats. The results collected with Styrofoam cups were similar but less discriminating than kongs. It potentially suggested that the difficulty level of the toy can affect the significance of the dogs’ preferences. No significant preference was observed when testing the treats with different ratio of the most and the least preferred protein sources, although the human descriptive panel was able to provide different profiles for the samples. In conclusion, the preference ranking procedure is a reliable test method but more research is necessary to further explore applications.

Dissertação de Mestrado Integrado em Medicina VeterináriaRecent studies show that the gut microbiome contributes to the vital physiologic and immunologic processes and is influenced by external factors such as diet, environment, medical interventions, and disease states. In this study, we describe the gut microbiome of healthy dogs and cats, from households and shelters, contributing for a better understanding of the effect that environment can have on it. The samples were collected between 2016 and 2017 and consisted of a household group (N=38, N=26 dogs and N=12 cats) and a shelter group (N=62, N=51 dogs and N=11 cats). DNA extraction was done directly from the faeces and the V4 region of the 16S rRNA gene was amplified, followed by sequencing using Illumina MiSeq. Raw sequences were treated using QIIME2 and Greengenes database was chosen for taxonomic classification alignment at 99% similarity. SAS statistical software was used, a p-value < 0.05 was considered. The Principal Coordinate Analysis plot demonstrated that the feline and canine microbiomes were well separated, as well as the household dog samples and the shelter dog samples, meaning that there is a difference in the gut microbiome between these groups. The same conclusion was not observed for the cat samples. The phyla Firmicutes and Bacteroidetes were the predominant ones in both species. For the dog samples, there was no difference between the two groups in Firmicutes and Bacteroidetes phyla (p>0.05), but the phyla Fusobacteria and Proteobacteria were in higher percentages in the shelter group (p<0.05). To our knowledge, this is the first study that describes and compares the gut microbiome composition of healthy household and shelter dogs and cats. This study demonstrates that the environment where animals are born and grow, as well as the amount of contact they have with humans, may have a great influence in their gut microbiome.
RESUMO - Microbioma entérico em cães e gatos saudáveis - Estudos recentes demonstram que o microbioma gastrointestinal tem um papel essencial nos processos fisiológicos e imunológicos do hospedeiro e que é fortemente influenciado pela dieta, ambiente, intervenções médicas e estados de doenças. Neste estudo pretendemos descrever o microbioma entérico de cães e gatos saudáveis provenientes de canis e de casas, contribuindo para uma melhor compreensão do efeito que o ambiente pode ter neste. As amostras foram colhidas entre 2016 e 2017 e consistiam num grupo de casa (N=38, N=26 cães e N=12 gatos) e um grupo de canil (N=62, N=51 cães e N=11 gatos). Foi realizada extração de DNA diretamente a partir das fezes e amplificada a região V4 do gene 16S rRNA, seguindo-se de sequenciação com Illumina MiSeq. As sequências foram tratadas usando o QIIME2 e a biblioteca Greengenes foi escolhida para classificação taxonómica, com o alinhamento a 99% de semelhança. Foi usado o SAS e considerado um p-value<0.05. O Principal Coordinate Analysis plot demonstrou que os microbiomas felino e canino são diferentes, assim como o microbioma de cães de casa e canil. No entanto, não foi possível chegar à mesma conclusão nas amostras de gato. Os phyla Firmicutes e Bacteroidetes foram os predominantes em ambas as espécies sendo que, nas amostras de cão, não houve uma diferença estatisticamente significativa entre os dois grupos para estes phyla (p>0.05). Os phyla Fusobacteria e Proteobacteria foram identificados com maior frequência nas amostras de canil, tendo sido esta diferença estatisticamente significativa (p<0.05). Tanto quanto é do nosso conhecimento, este é o primeiro estudo a descrever e comparar o microbioma gastrointestinal de cães e gatos saudáveis provenientes de casa e canil. Este estudo demonstra que o ambiente em que os animais nascem e habitam, assim como a quantidade de contacto que têm com o ser humano, pode ter grande influência no seu microbioma gastrointestinal.

Full textAbstract:
A clinical trial was undertaken using three different inhalant anaesthetic agents and one intravenous anaesthetic agent in dogs undergoing routine desexing surgery. Healthy adult dogs undergoing either ovariohysterectomy or castration were assessed as to their demeanour, with the more excitable dogs being placed in groups receiving premedication with acepromazine and morphine. All dogs were then randomly assigned an anaesthetic agent for induction of general anaesthesia. The agents were the inhalants halothane, isoflurane and sevoflurane, and the intravenous agent propofol. Inhalant inductions were undertaken using a tight fitting mask attached to a standard anaesthetic machine with a rebreathing circuit, with the maximum dose of inhalant available from a standard vaporiser. Propofol inductions were undertaken via intravenous catheter. Dogs induced with propofol were randomly assigned one of the three inhalant agents for maintenance. Those induced by inhalant agent were maintained using the same agent. The surgical procedure was undertaken in standard fashion, as was recovery from anaesthesia. All dogs received the non-steroidal anti-inflammatory agent meloxicam. Data collection was divided into three stages: induction, maintenance, and recovery from anaesthesia. Variables measured at induction of anaesthesia were time to intubation, number of intubation attempts, tolerance of mask, quality of induction and quality of transfer to the maintenance stage. Standard variables for monitoring of anaesthesia were recorded throughout the maintenance of anaesthesia. Variables measured at recovery were time to righting, time to standing and quality of recovery. The mean time to intubation when using the newer inhalant sevoflurane (196.2 � 14.8sec, mean � SE) was not significantly different to that for halothane (221.4 � 14.0sec) or isoflurane (172.4 � 15.0sec). Time to intubation with isoflurane was significantly faster than with halothane. Mean time to intubation with propofol (85.4 � 7.7sec) was significantly faster than that for any of the three inhalants. Choice of inhalant had no effect on quality of induction. The use of premedication significantly improved the quality of induction. The use of propofol for induction likewise significantly improved the quality of induction. Standard cardiorespiratory variables measured during the maintenance phase of anaesthesia remained within normal clinical ranges for all three inhalants, and were therefore not further analysed. Choice of inhalant agent had no significant effect on the time to righting or standing in recovery. The use of propofol for induction had no effect on these variables. Animals placed in groups receiving premedication had significantly longer times to righting and standing. The oesophageal temperature at the end of the procedure had a significant effect on times to righting and standing, with lower temperatures contributing to slower recoveries. Independent of procedure time, male dogs had shorter times to righting than female dogs.

Full textAbstract:
Kangal dogs are the most popular dogs of Turkey due to their strength, intelligence, loyalty, endurance to extreme temperatures and their lack of predatory behavior towards livestock. In this study to provide genetic information about the distinctness of Kangal and Akbash dogs and hence to provide a basis to conserve them separately, 585 base pair of the mitochondrial DNA (mtDNA) control region sequence was analysed in 105 Kangal and 9 Akbash dog samples. All the results indicated that Kangal and Akbash dogs were different from each other. Comparison of the Turkish data with those from other dogs revealed that Kangal dogs harbour a rare haplogroup which is only seen in Scandinavian (36%), Portuguese (20%), Turkish (20%) dogs and only one Spanish dog, but not in Akbash, Middle Eastern, other European, Eastern Asian and Indian dogs. Furthermore, comparison of the Kangal and Akbash dogs with the dogs from different geographic regions indicated that Kangal dogs are genetically closer to Scandinavian and South West Asian dogs whereas Akbash dogs are more similar to European and East Asian dogs, based on the mtDNA control region sequences Today, the sizes of Kangal and especially Akbash populations are decreasing. An urgent program for their conservation is needed. In order to conserve them separately, it must be understood that these two dogs are genetically distinct. That is why, the main purpose of the present study is to provide genetic information about the distinctness of Kangal and Akbash dogs.

Full textAbstract:
In the Great Plains, sylvatic plague (Yersinia pestis), poisoning, and habitat conversion continue to reduce and fragment black-tailed prairie dog (Cynomys ludovicianus) habitat in which burrowing owls (Athene cunicularia) seek shelter and nest sites. Consequently, burrowing owls are experiencing population declines at the periphery of their range. The objective of this research was to evaluate habitat factors affecting a population of burrowing owls at the eastern extent of their range. I modeled hypothesized relationships between nest density (Chapter 2) and colony productivity (Chapter 3) and prairie dog habitat characteristics at two scales on the Bad River Ranches, South Dakota. Colony size, prairie dog and total burrow density, mean nearest neighbor and mean nest-to-colony edge distances, cover of warm-season grasses, and soil texture were variables measured at the colony level. Landscape level variables included the degree of colony isolation and the topographic location of colonies. In Chapter 4, I evaluated the spatial distribution of nests within colonies. Twenty-six prairie dog colonies were surveyed for burrowing owl nests during the 2005 (n =10) and 2006 (n = 16) breeding seasons. I evaluated competing models of nest density using a likelihood cross-validation approach. The model selection results in Chapter 2 suggested the top a priori predictor of nest density was colony size. Nest density was greatest on small colonies (<20 ha) and lowest on large colonies (>40 ha); in contrast, owl numbers were higher on large colonies. Exploratory analysis identified the interaction between cover of bare ground and colony habitat as the best approximating model of nest density. In Chapter 3, competing models of colony productivity were assessed. Although an additive model containing the degree of isolation, habitat, and colony size had a positive effect on colony productivity, exploratory analysis suggested colony size and the degree of isolation had the strongest influence. In Chapter 4, results showed that owls displayed a strong preference for nesting near colony perimeters, but this did not translate to higher productivity. The associations I observed lend support for the value of maintaining prairie dog colonies to ensure the persistence of burrowing owl populations in the Great Plains ecosystem.

Background: Canine hypothyroidism is thought to cause abnormalities in glucose homeostasis, but the effect on glucose tolerance and insulin sensitivity has not been determined to date.
Hypothesis/Objectives: The purpose of the study was to investigate whether hypothyroidism has an effect on glucose tolerance and insulin sensitivity in dogs. We hypothesized that hypothyroidism causes insulin resistance.
Animals: Sixteen euthyroid bitches were randomly selected and allocated into two groups. In 8 dogs, hypothyroidism was induced by administration of 1 mCi/kg I-131. Experiments were performed on non-anesthetized, fasted dogs in anestrous approximately 12 months after hypothyroidism was induced.
Methods: The insulin-modified frequently sampled intravenous glucose tolerance test (FSIGT) and minimal model analysis were used to determine basal insulin and glucose concentrations, acute insulin response to glucose (AIRg), insulin sensitivity (SI), glucose effectiveness (SG) and the disposition index (DI).
Results: In the hypothyroid group, basal glucose concentrations were mildly decreased (P = 0.0079), whereas basal insulin was increased (P = 0.019). Insulin sensitivity was reduced in the hypothyroid group (P<0.001), whereas AIRg was higher (P=0.01). Other parameters were not different between groups.
Conclusions/Clinical Importance: Hypothyroidism negatively affects glucose homeostasis by inducing insulin resistance. In hypothyroid dogs, the disposition index (insulin sensitivity x insulin secretion) remained unchanged due to a compensatory increase in insulin secretion, thereby maintaining glucose tolerance. In cases with impaired insulin secretion, such as canine diabetes mellitus, concurrent hypothyroidism can have important clinical implications in the successful management of the disease.Master of Science

Full textAbstract:
Stress in dogs can contribute to behavioural problems which may lead to rehoming or euthanasia of the dog. The aim of this study was to investigate how dog characteristics correlated to stress, whether it is possible to detect behavioural problems in order to treat the dogs. Twenty-two dogs were evaluated according to their behavioural problem by a veterinarian and a dog trainer. The dogs participated in a behavioural and physiological test, and the results were compared to characteristics gathered by a Canine Behavioural Assessment and Research Questionnaire (C-BARQ), filled in by the dogs’ owners. The result showed that the total amount of stress related behaviour correlated positively to the C-BARQ score for attachment and attention-seeking behaviour and had a tendency of positive correlation to energy level and owner-directed aggression. Both the veterinarian behavioural problem score and trainer behavioural problem score had a tendency of positive correlation to stranger-directed fear. Dogs that, according to the C-BARQ, were found to be very attached and attention-seeking, showed high energy level or owner-directed aggression were likely to show stress related behaviours during the test in my study. By addressing the stress, the behavioural problems may be eased.
