Medical Genetic Behavioral Risk Factors Of Pyrenean Shepherds

This book (Pyrenean Shepherd ) provides you with a through description and positive attributes of this breed including origin, purpose, history, normal heights and weights, acceptable colors and behavioral traits. Our books differ from most books on dog breeds because this book also provides you with a comprehensive and authoritative source of all the known predisposed hereditary health syndromes for the breed. You will find extensive references for each problem described. We also provide the breed club address for this breed and a list of laboratories and organizations that can provide professional help and information. As a small animal veterinarian, I have always been intrigued by the way dogs have been bred to fill a purpose in life and further impressed that they also tend to love performing that service. Greyhounds and other sight hounds are built for speed with aerodynamic bodies consisting of small head, deep chest, narrow waist and large leg muscles. On the other hand Dachshunds take their name from German words meaning “badger dog” and they use their long nose, long body and short legs to both track, enter and dig into badger dens. After developing a practice that catered to clients with show dogs, my interest in each breed continued to grow as I studied and observed more and more about the unique predisposition and incidence of health problems in each breed. Breeders of purebred dogs for show were a challenge and inspirational for me to research and help them with their unique health problems. Historically references to hereditary problems are scattered throughout various Veterinary medical texts and journals such as ophthalmology, neurology, gastroenterology, cardiovascular and dermatology. This book, as well as the other books and articles I have written, is researched and compiled with the intention to provide both veterinarians and dog owners with comprehensive and authoritative predisposition information under the breed name. At the date of this publication, The American Kennel Club Canine Health Foundation and the The Kennel Club of England reports over 400 known hereditary health syndromes throughout the dog kingdom. At the writing of my first book in 1983, less than 50 hereditary issues are able to be predicted and or diagnosed. Sequencing of the canine genome, DNA tests, metabolic testing including blood tests and urine testing; plus, phenotypic examinations such as radiographs, ultrasound, and CERF or OFA eye registry exams by a Board Certified Veterinary Ophthalmologist have advanced the science of breed related health and behavioral problems. This book will provide veterinarians, researchers, pet owners and breeders with a comprehensive guide to all the known problems veterinarians and dog owners should consider during pet selection and throughout each life stage of our canine friends.

In Designing Strategies for Cleft Lip and Palate Care it was aimed to link the epidemiology from different areas in the world with the interspecialty surgical care and the future genetic research projects. The objective is to concisely discuss the methodology of interspecialty care and stimulate future ideas for prophylactically managing or preventing such deformities. I am confident that one day the surgical interventions that bombard the patients from the day of newborn delivery and throughout the years of youth should be significantly decreased based on the genetic prophylactic intervention, probably.

Dogs, Canis familiaris, share the lives of humans all over the world. That dogs, and the behavior of dogs, are of interest to many is therefore no surprise. In this thesis, the main aim has been to identify factors that affect dogs’ behaviours. The dog, Canis familiaris, is our first domesticated animal. Since domestication, various types of dogs have developed through adaptation to an environment shared with humans and through our selective breeding, resulting in a unique variation in morphology and behaviour. Although there is an individual variation in the behaviour of dogs, there is also a difference between breeds. Moreover, selection during the last decades has split some breeds into divergent types. Labrador and golden retrievers are divided into a common type, for show and companionship, and a field type, for hunting. By comparing the breed types, we can study the effects of recent selection. In Paper I, we investigate differences in general behavioural traits between Labrador and golden retriever and between common and field type within the two breeds by using results from the standardized behaviour test Dog Mentality Assessment. There were differences between breeds and types for all behavioural traits. However, there was also an interaction between breed and type. Thus, a common/field-type Labrador does not behave like a common/field-type golden retriever. Even though they have been selected for similar traits, the selection has affected the general behavioural traits differently in the two breeds. In paper II, we were interested in dogs’ human-directed social skills. Dogs have a high social competence when it comes to humans. Two experiments commonly used to study these skills are the problem-solving test, where dogs’ human-directed behaviours when faced with a problem are measured, and the pointing test, where dogs are tested on how well they understand human gestures. We compared the social skills of German shepherds and Labrador retrievers, and of common- and field-type Labradors. Labradors were more successful in the pointing test and German shepherds stayed closer to their owners during the problem solving. Among Labrador types, the field type had more human eye contact than the common type. Importantly, when comparing the two experiments, we found no positive correlations between the problem-solving test and the pointing test, suggesting that the two tests measure different aspects of human-directed social behaviour in dogs. A previous study has identified two suggestive genetic regions for human-directed social behaviours during the problem-solving test in beagles. In paper III, we show that these SNPs are also associated to social behaviours in Labrador and golden retrievers. Moreover, the Labrador breed types differed significantly in allele frequencies. This indicates that the two SNPs have been affected by recent selection and may have a part in the differences in sociability between common and field type. The behaviour of dogs cannot simply be explained by genetics, there is also an environmental component. In paper IV, we study which factors that affect long-term stress in dogs. Long-term cortisol can be measured by hair samples. We found a clear synchronization in hair cortisol concentrations between dogs and their owners. Neither dogs’ activity levels nor their behavioural traits affected the cortisol, however, the personality of the owners did. Therefore, we suggest that dogs mirror the stress level of their owners. The mediator between genes and the environment is epigenetics, and one epigenetic factor is DNA methylation. In paper V, we compared methylation patterns of wolves and dogs as well as dog breeds. Between both wolves and dogs and among dogs there were substantial differences in methylated DNA regions, suggesting that DNA methylation is likely to contribute to the vast variation among canines. We hypothesize that epigenetic factors have been important during domestication and in breed formation. In this thesis, I cover several aspects on how dogs’ behaviours can be affected, and paint an intricate picture on how genetics, epigenetics, and human-dog relations forms dog behaviour.
