The classic study of canine behavior: “A major authoritative work…Immensely rewarding reading for anyone concerned with dog-breeding.”—Times Literary Supplement Based on twenty years of research at the Jackson Laboratory, this is the single most important and comprehensive reference work on the behavior of dogs ever compiled, written by geneticist and comparative psychologist John Paul Scott, known for his research into social behavior and aggression. “One of the most important texts on canine behavior published to date. Anyone interested in breeding, training, or canine behavior must own this book.”—Wayne Hunthausen, D.V.M., Director of Animal Behavior Consultations “This pioneering research on dog behavioral genetics is a timeless classic for all serious students of ethology and canine behavior.”—Dr. Michael Fox, Senior Advisor to the President, The Humane Society of the United States “Comprehensive…[a] seminal work.”—Mark Derr, The Atlantic Monthly “Essential reading for anyone involved in the breeding of dogs. No breeder can afford to ignore the principles of proper socialization first discovered and articulated in this landmark study.”—The Monks of New Skete, authors of How to Be Your Dog's Best Friend and the video series Raising Your Dog with the Monks of New Skete

This book highlights the state of the field in the new, provocative line of research into the cognition and behavior of the domestic dog. Eleven chapters from leading researchers describe innovative methods from comparative psychology, ethology and behavioral biology, which are combined to create a more comprehensive picture of the behavior of Canis familiaris than ever before. Each of the book’s three parts highlights one of the perspectives relevant to providing a full understanding of the dog. Part I covers the perceptual abilities of dogs and the effect of interbreeding. Part II includes observational and experimental results from studies of social cognition – such as learning and social referencing – and physical cognition in canids, while Part III summarizes the work in the field to date, reviewing various conceptual and methodological approaches and testing anthropomorphisms with regard to dogs. The final chapter discusses the practical application of behavioral and cognitive results to promote animal welfare. This volume reflects a modern shift in science toward considering and studying domestic dogs for their own sake, not only insofar as they reflect back on human beings.

“Based on the latest findings in the field of canine cognition and behavior, this book is an invaluable resource.” —Hal Herzog, author of Some We Love, Some We Hate, Some We Eat: Why It's So Hard To Think Straight About Animals Every dog owner knows that along with the joy can come the stress and frustration of behavioral problems, which are expensive to diagnose and treat. Enter Kim Brophey, award-winning canine behavior consultant. Using cutting-edge research, Brophey has developed a groundbreaking system that allows owners to identify what their dog is struggling with, why, and how they can fix it. Brophey’s approach is unlike anything that has been published before and will give dog owners a new understanding of what motivates and affects their dog’s behavior. This innovative technique rethinks the way we categorize dogs, and distills information from over twenty scientific disciplines into four comprehensive elements: learning, environment, genetics, and self. With revolutionary tips for specific dog breeds, this book will change dog owners’ lives—and lead to happier human-canine relationships. “It’s refreshing to finally find a book that takes into consideration the many predispositions to behavior problems in dogs . . . teaches us to really see the dog in its entirety.” —Alexandre Rossi, author of A Dog at the Keyboard

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.

The domestic dog has many phenotypic and behavioral forms. In this chapter we describe five different kinds of dogs and how each has been derived. We trace the background village dog adapting to the age of agriculture, with the coincident transformation of human behavior to permanent settlement. Over centuries, this village dog has changed, adapting to its different geographies and to local agricultural activities. In tandem, people began sorting through the village populations for dogs with appropriate behaviors, and these eventually became the founding stock for breeding programs. In recent centuries, samples of these working and hunting breeds have been collected by kennel clubs, and sexually isolated, becoming at best historic representations of the working or hunting breeds. More commonly they are used as pets, or household dogs, sometimes with sport competitions in the show or agility ringl

Humans have bred dogs for physical and behavioral characteristics for millennia. These efforts can have unintended side effects, however, which may be either advantageous or cause issues - such as a predisposition to certain medical complaints, or, controversially, behavioural issues. The scientific study of domestic dogs is still in its infancy, but public demand for this information is at a record high as more and more pet owners seek to understand their canine family members. Focusing on the behavioral differences and tendencies that have arisen in different breed lines, this book explores, summarizes, and explains the scientific evidence on what breed can tell us about behaviour - and, crucially, what it cannot. Providing a comprehensive and approachable view of the science behind breed-specific behaviors, this book gives dog enthusiasts from all professional and personal backgrounds a better understanding of why dogs do what they do, and how we can improve our relationships with our canine companions. Covering genetics, phylogeny of canids, temperament, aggression, social behavior, and the history of dog breeding, it is an important read for researchers, students, veterinary practitioners and animal behaviourists, as well as shelter staff, dog trainers, or anyone looking for a greater understanding of dog breed differences.

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.
