Abstract (sommario):

Dogs are popular pets in many countries. The interactions that occur between dogs, and between dogs and humans, are of interest to behavioural, welfare, psychological and social sciences. As dogs are a potential source of zoonotic infections to humans, such interactions may also impact on public health. Interactions between dogs, for example whilst walking, may also transfer infectious diseases (zoonotic or non-zoonotic) through the pet dog population. Despite their popularity as pets, there have been no in-depth studies into the contacts that occur between dogs, and between dogs and people; this thesis uses a variety of methodologies to examine these contacts. A census-based, epidemiological study was used to investigate factors associated with dog ownership and contact with dogs, in a semi-rural community of 1278 households in Cheshire, UK. This study supported the suggestion that dogs are more common in families who have older children (6-19 years), as has been generally observed in other countries. Dog owners were also more likely to have contact with dogs other than their own, compared with those not owning a dog. A questionnaire survey of 260 dog owning households in this community found that the contacts that these dogs have, with people and other dogs, were highly variable and affected by: size, gender and age of dog; individual dog behaviours; human behaviours and human preferences in management of the dog. A number of situations were identified that may be of particular importance in relation to zoonoses, including: sleeping areas, playing behaviours, greeting behaviours, food sources, walking, disposal of faeces, veterinary preventive treatment and general hygiene. Faecal samples were provided for 183 of the dogs and forty-six (25%) were identified, by either culture or direct PCR isolation methods, as carriers of the zoonotic pathogen Campylobacter upsaliensis. Multivariable logistic regression identified risk factors for C. upsaliensis carriage as: living with another positive dog; living in a household with pet fish; size of dog; age of dog; being fed commercially-bought dog treats; and being fed human food tit-bits (particularly the act of feeding leftovers in the bowl, although letting the dog feed directly from a plate had a protective effect). These results have implications for prevention of C. upsaliensis carriage in pet dogs and the subsequent possible transmission to people. Social network analytical approaches were used to investigate potential networks arising amongst 214 of the dog owning households, through their utilisation of public space during walking. A high level of potential contact was demonstrated and this has implications for infectious disease transmission. Most households walked their dogs in only a few areas, but a small number visited many areas. In addition, behavioural observational studies of focal dogs were used to investigate the interactions with other dogs, people and the environment that may occur on dog walks. Dogs were observed to interact with other dogs much more commonly than with people. A multivariable model of percentage duration spent sniffing suggested that day of observation, UK Kennel Club Breed Type and observing urination were important. Whether a dog is on lead or not whilst on a walk: could affect the frequency in which it interacts with other dogs and people that it meets. An experimental study of ten dogs was conducted and hierarchical multilevel modelling suggested that lead status of both dogs in an interaction is important in influencing whether or not the interaction will occur; therefore if used as an intervention for reducing disease spread, both dogs should be on a lead. The work in this thesis provides new insight into the dog-human. relationship and presents information of use to those interested in reducing infectious disease transmission between dogs, and between dogs and people.

Abstract (sommario):

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.

Testo completo

Abstract (sommario):

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.

Testo completo

Abstract (sommario):

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.

Abstract (sommario):

In today’s world, more than 400 different dog breeds have been registered and the number continues to increase, as people come up with new ways of breeding dogs. Purebred dogs are prone to many inherited disorders, inbreeding depression and a decreasing gene pool. Mixed-breed dogs, on the other hand, are said to be less prone to these problems, as they have a higher genetic variation. This review combined knowledge from the last 25 years of research in the field of mixed-breed dogs and purebred dogs to see what we know and what we still need to examine further. The literature all in all agrees that mixed-breed dogs have an increased longevity, although other factors determine longevity other than breed. They also have a decreased risk of some of the major diseases such as organ disorders and cancer but are instead prone to other problems such as ruptured cranial cruciate ligament, behavioural problems such as aggression, accidents and diabetes. Future research needs to take the inverse relationship of body mass and longevity into account when measuring longevity between breeds and more studies should be made in the field of canine cancer, as this accounts for most deaths overall in dogs.
I dagens värld har mer än 400 olika hundraser registrerats och antalet fortsätter att öka gradvis, eftersom människor kommer med nya sätt att avla hundar. Renrasiga hundar kan ha stora problem med ett flertal ärftliga störningar, inavelsdepression och en minskande gen pool. Å andra sidan sägs hundar med blandad ras vara mindre benägna för dessa problem, eftersom de har en högre genetisk variation. Denna översyn sammanfattar kunskap från de senaste 25 årens forskning inom området blandade hundar och renrasiga hundar för att se vad vi vet och vad vi fortfarande behöver undersöka ytterligare. Litteraturen är överens om att hundar med blandad ras har en ökad livslängd, även om andra faktorer avgör livslängder än rasen. De har också en minskad risk för några av de huvudsakliga sjukdomarna som organ defekter och cancer, dock kan de ha andra problem såsom brustet kranialkorsband, beteendeproblem som aggression, olyckor och diabetes, vilket påverkar livslängden. Framtida forskning måste ta hänsyn till det omvända förhållandet mellan kroppsmassa och livslängd vid mätning av livslängd mellan raser. Fler studier bör göras inom området cancer hos hundar, eftersom detta står för de flesta dödsfall totalt sett hos hundar.

Testo completo

Abstract (sommario):

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.

Abstract (sommario):

Nearly all of the histories of Shays's Rebellion point to debt as the reason why farmers in western Massachusetts rose against the courts and the state government in the fall and winter of 1786-87. Recent scholarship demonstrates a new line of reasoning based on the tax records of those involved. The following thesis, a screenplay, offers a fictional telling of this insurgency. The story is told using language pulled from contemporary letters and documents and follows a line of causation pointing to inequitable state tax structure and poor representation as the provocation. The response that ensued was not a rebellion – it was a Regulation.

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.

Abstract (sommario):

Accidental behavior chains are a common problem in dog training. Many handlers inadvertently reinforce undesirable behaviors. The behavior analytic literature already contains articles describing methods of breaking chains; however, those methods either are not used in dog training for practical purposes or are ineffective in dog training. This experiment investigated two ways to break a behavior chain, including extending the chain and introducing a delay into the chain. The results of extending the chain showed that it is possible to decrease the target behavior using this method, but it was not eliminated in this study. Adding a delay into the behavior chain resulted in a quick elimination of the target behavior.

Abstract (sommario):

Domestic dogs have co-habited with humans for at least 15000 years. Close social interaction between the two species has promoted inter-specific communication and dogs now show advanced skills in responding to human signals in comparison to wolves. However, research into dogs' abilities to interpret human signals has predominantly focussed on visual gestures, while their responses to vocal signals remain under-investigated. Exploring the perception of human speech by dogs, a phylogenetically distant species, could provide new insights into the evolution of mammal communication. Therefore, the aim of this thesis is to assess human speech perception by dogs. Speech is composed of two main communicative components: the segmental phonemic cues carrying the linguistic content and the supra-segmental cues transmitting information about the speaker such as their gender, age and emotional state. I first explore how dogs perceive supra-segmental cues, determining that they are capable of the cross-modal discrimination of human gender. I then provide a review detailing the mechanisms underlying cross-modal associations in mammal communication, before testing which of these mechanisms may enable dogs to cross-modally associate cues to human age. The results indicate that dogs learn to match some voices to humans according to their age category, while also perceiving more general cross-modal correspondences in the environment. Finally, I investigate how dogs dissociate the main communicatory components of speech during processing, providing evidence that dogs differentially process segmental and supra-segmental cues according to their communicative content. In doing so, dogs appear to express parallel hemispheric biases to those reported in humans. Additionally, the results provide the first clear demonstration that dogs attend to the combinatory structure of the phonemic content in learnt commands. Overall, this thesis extends our knowledge of dogs' perception of human signals, indicating that they are capable of perceiving each of the main components of speech in a functionally relevant manner. Together the results suggest that dogs share some of the cognitive and social processes involved in speech perception with human listeners.

Abstract (sommario):

Working dogs contribute to many human endeavours. However, minimal research exists into Australia’s largest group of working dogs – the livestock herding dog. This knowledge gap exposes the sector to the risks of sub-optimal efficiency, compromised productivity and unacceptable animal welfare outcomes. This thesis aims to address this void by characterising the problem of livestock herding dog wastage and contributing to the incremental process of improving management, selection and breeding practices. Data from a questionnaire completed by 812 livestock herding dog owners on 4,027 dogs revealed that livestock working dogs typically provide a lifelong working contribution valued at approximately A$40,000, representing a 5.2-fold return on investment. At least 20% of livestock herding dogs are culled prematurely from work. Behavioural causes were cited for 89% of these failures. Management and owner characteristics associated with failure rates included; acquisition practices, housing methods, training approach, exercise frequency and owner personality and attitude to investment in their dog. To identify traits important to success, a selective sweep analysis comparing the genomic haplotype architecture of working and show Kelpies was undertaken. In the working Kelpie, a selective sweep spanning three megabases on chromosome 3 was identified in the region of genes related to fear-memory formation and pain perception. The Herding Dog Assessment Form - Personality (HDAF-P) was devised to collect behavioural data on herding dogs. Application of the HDAF-P to 261 working Kelpies provided a database of behavioural scores for 17 traits salient to working ability with those correlated most strongly to the owner’s assessment of overall ability being revealed as; initiative (T = 0.42, p < 0.001), intelligence (T = 0.38, p < 0.001), persistence (T = 0.38, p < 0.001), confidence (T=0.37, p < 0.001) and calmness (T=0.32, p < 0.001).

Abstract (sommario):

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.

Abstract (sommario):

The desire I have to make visual images has been fueled by my interest in the parley between man and animal. Throughout history, artists have been intrigued by the relationship between man and animal, an intrigue which has evolved into sane contemporary work.Through this series of nine paintings, the message I impart is the importance of mankind's consideration of animal welfare and that animals are dignified, capable of selfhood and deserving of respect.Through the use of them as my subjects, my dogs, Zeek and Hogan, become the domesticated messengers. I use vivid color, odd perspectives, natural poses and environments, the incorporation of pattern and thick application of the paint to convey my opinions.I learned more about myself and my relationship to the dogs who share my life. It is important to me to make images of my feelings about animals and to educate others about the importance of their well-being.

Abstract (sommario):

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.

Abstract (sommario):

Accidental poisoning of domestic dogs is an unfortunate occurrence when using poison baits to control introduced pests such as feral cats, red foxes, and wild dogs. This study aimed to investigate how dog breed (i.e., toy, terrier, sporting, domestic working and working dogs) and temperament influence aversion methods. Using non-poisonous baits and a device which emits a small electrical correction, domestic dogs were trained to avoid commercially-available non-toxic FoxOff® baits. Fifty-six dogs were recruited through online media services (e.g., Facebook). Each dog underwent four sessions of ‘one-on-one’ learned aversion training, spread across 6 weeks where individual dogs were subjected to a small electrical correction after having touched a non-toxic bait that has been attached to the training device and earthing rod (this created an electrical charged bait). Each dog’s behaviour, temperament and level of trainability were monitored during each session, based on temperament and behavioural test guidelines and procedures. Dog breeds were categorised based on their level of trainability; easy (i.e., only one to two training sessions and one to two repetitions of electrified baits during those sessions were required), moderate (i.e., only two to three training sessions and two to three repetitions of electrified baits during those training sessions were required), and difficult (i.e., all four training sessions and three repetitions of electrified baits during those four training sessions were required). The results indicated that 50 dogs were successfully trained to avoid the bait and that temperament and breed significantly influenced their level of trainability. Moreover, specific temperaments of obedience, excitability, playfulness and boldness were significantly related to each of the dog breeds respectively. Terriers were classified as having a difficult level of trainability; sporting and domestic working dogs displayed a moderate level of trainability, and working and toy dogs presented with easy levels of trainability based on their behavioural responses during the four training sessions. Furthermore, the temperament traits boldness (negatively correlated with trainability), fearfulness and anxiousness (positively correlated with trainability) significantly influenced dog trainability. This study demonstrated that learned aversion training with domestic and working dogs of different breeds and temperaments has future potential in relation to the development and implementation of practices involving learned aversion training methods for dogs.

Abstract (sommario):

Livestock guarding dogs (LSGDs) have been used for centuries to reduce depredation on livestock and more recently, to facilitate the conservation of threatened predator species. Conservation NGOs (non-government organisations) in southern Africa promote the use of Anatolian Shepherds as LSGDs. However, livestock farmers in Botswana have been using a variety of different breeds for this purpose, including the local mixed-breed “Tswana” dogs. Postal, telephonic and face-to-face interview questionnaires were administered to 108 livestock farmers in Botswana to gauge how their LSGDs were being used, in order to determine what factors contributed to the success and affordability of these dogs. Eighty-three percent of farmers had LSGDs which equaled or decreased livestock depredations on their farms, with an average reduction in livestock depredation of 75% per year. This equated to an average saving of US$2,017 annually per farm. The costs of purchasing (average US$27) and maintaining the 198 LSGDs in my study (average US$169/LSGD/year) were very low compared to other countries and helped contribute to the high profits obtained by farmers (average US$1,497/farm or US$789/LSGD). A unique investigation of different breeds was possible due to the diverse array of breeds in the sample (Anatolian Shepherds, Cross Breeds, Tswana dogs, Greyhounds and Pitbulls), with the crossbreed dogs (Crosses and Tswana LSGDs) performing the best. LSGDs that reduced depredation and had minimal behavioural problems were the most likely to incite positive changes in their owners in regards to attitudes towards predators. Sixtysix percent of farmers stated that they were more tolerant of predators since obtaining a LSGD, and 51% reported that they were less likely to kill predators since obtaining a LSGD. My results indicate that successful, well-behaved LSGDs are a cost-effective tool that has the ability to increase farm productivity and improve predator-farmer conflicts in Botswana. The methods recommended in my thesis, in particular the benefits of using local breeds of dog as LSGDs, can be implemented on farming practices the world over to assist farming productivity and to promote conservation efforts.
