Dogs have become the subject of increasing scientific study over the past two decades, chiefly due to their development of specialized social skills, seemingly a result of selection pressures during domestication to help them adapt to the human environment. The Social Dog: Behaviour and Cognition includes chapters from leading researchers in the fields of social cognition and behavior, vocalization, evolution, and more, focusing on topics including dog-dog and dog-human interaction, bonding with humans, social behavior and learning, and more. Dogs are being studied in comparative cognitive sciences as well as genetics, ethology, and many more areas. As the number of published studies increases, this book aims to give the reader an overview of the state of the art on dog research, with an emphasis on social behavior and socio-cognitive skills. It represents a valuable resource for students, veterinarians, dog specialists, or anyone who wants deeper knowledge of his or her canine companion. - Reviews the state of the art of research on dog social interactions and cognition - Includes topics on dog-dog as well as dog-human interactions - Features contributions from leading experts in the field, which examine current studies while highlighting the potential for future research
Behavior is shaped by both genetics and experience--nature and nurture. This book synthesizes research from behavioral genetics and animal and veterinary science, bridging the gap between these fields. The objective is to show that principles of behavioral genetics have practical applications to agricultural and companion animals. The continuing domestication of animals is a complex process whose myriad impacts on animal behavior are commonly under-appreciated. Genetic factors play a significant role in both species-specific behaviors and behavioral differences exhibited by individuals in the same species. Leading authorities explore the impact of increased intensities of selection on domestic animal behavior. Rodents, cattle, pigs, sheep, horses, herding and guard dogs, and poultry are all included in these discussions of genetics and behavior, making this book useful to veterinarians, livestock producers, laboratory animal researchers and technicians, animal trainers and breeders, and any researcher interested in animal behavior. - Includes four new chapters on dog and fox behavior, pig behavior, the effects of domestication and horse behavior - Synthesizes research from behavioral genetics, animal science, and veterinary literature - Broaches fields of behavior genetics and behavioral research - Includes practical applications of principles discovered by behavioral genetics researchers - Covers many species ranging from pigs, dogs, foxes, rodents, cattle, horses, and cats
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.
Is it heredity or environment that shapes the dog? Researchers J.P. Scott and John L. Fuller, authors of Genetics and Social Behavior of the Dog, bred and cross-bred dogs in their quest to understand human heredity and behavior. Their research yielded a gold mine of data that Pfaffenberger turned into practical information for dog breeders and trainers. Learn about the critical stages of puppy development, how breed differences make dogs suitable for specialized work, and how to breed and socialize temperamentally sound dogs.

The biological and genetic bases of behavioral diversity have long been topics of study within many disciplines, including evolutionary biology, genetics, ethology, sociobiology, and comparative psychology, but only relatively recently have attempts been made to bring these different approaches together. This volume covers a wide range of interdisciplinary research which uses some of the newest and most promising methods and technologies. Presented here is an overview of findings in the ongoing search for the ultimate causes of behavior in several different species, including primates, dogs, rodents, birds, and fish. Divided into five parts, the work describes research on sexual and kin selection, personality and temperament, molecular genetics of personality, color vision and body coloration, and the neurological underpinnings of complex behaviors. Valuable for researchers as well as graduate students in a wide range of fields from neuroscience to ecology, the book is also useful to those seeking to move beyond the boundaries of their own discipline and to expand their knowledge.
Dogs have been mankind's faithful companions for tens of thousands of years, yet today they are regularly treated as either pack-following wolves or furry humans. The truth is, dogs are neither -- and our misunderstanding has put them in serious crisis. What dogs really need is a spokesperson, someone who will assert their specific needs. Renowned anthrozoologist Dr. John Bradshaw has made a career of studying human-animal interactions, and in Dog Sense he uses the latest scientific research to show how humans can live in harmony with -- not just dominion over -- their four-legged friends. From explaining why positive reinforcement is a more effective (and less damaging) way to control dogs' behavior than punishment to demonstrating the importance of weighing a dog's unique personality against stereotypes about its breed, Bradshaw offers extraordinary insight into the question of how we really ought to treat our dogs.
Written for the layperson and the scientist alike, this study of how heredity affects physical and behavioral conditions in dogs includes basic genetic principles, polygenic inheritance, inheritance of many desirable and undesirable features, genetic diseases, and much more.
If you breed dogs for any reason, you must own this book. Genetic diseases are among the most serious hazards on the landscape of modern dog breeding and one of the most vexing challenges facing today's dog breeders. Is it appropriate to open the gene pool to unwanted conditions in the pursuit of physical perfection, or must breeding to the Standard take a back seat to producing healthy animals? In Control of Canine Genetic Diseases, renowned authority George A. Padgett, DVM, provides an expert road map to help dog breeders everywhere avoid the pitfalls they are almost destined to encounter. For anyone whose goal is to produce healthy, functional and beautiful dogs, this is the book they need. Dr. Padgett provides clear explanations of modes of inheritance, how to conduct and analyze test matings and how to lower the chances of producing affected animals. Numerous tables, diagrams and graphs further enhance the text to facilitate the breeder's understanding. A Howell Dog Book of Distinction
