  1. Pre- and Post-Race Intestinal Microbiota in Long-Distance Sled Dogs and Associations with Performance

    Full-text: Available

    | Contributor(s):: Kristoffer Relling Tysnes, Inga Leena Angell, Iselin Fjellanger, Sigrid Drageset Larsen, Silje Rebekka Søfteland, Lucy J. Robertson, Ellen Skancke, Knut Rudi

    Although our understanding of the role of the gut microbiota in different diseases is improving, our knowledge regarding how the gut microbiota affects functioning in healthy individuals is still limited. Here, we hypothesize that the gut microbiota could be associated with sled dog...

  2. Aggressiveness, ADHD-like behaviour, and environment influence repetitive behaviour in dogs

    | Contributor(s):: Sulkama, S., Salonen, M., Mikkola, S., Hakanen, E., Puurunen, J., Araujo, C., Lohi, H.

  3. Ethnographic Observations on the Role of Domestic Dogs in the Lowland Tropics of Belize with Emphasis on Crop Protection and Subsistence Hunting

    | Contributor(s):: Pacheco-Cobos, Luis, Winterhalder, Bruce

  4. Use of questionnaire-based data to assess dog personality

    Full-text: Available

    | Contributor(s):: Pamela Wiener, Marie J. Haskell

    The study of dog personality is of general academic interest and also has applications for the management of both working dogs and pets. However, acquiring direct behavioral assessments of large numbers of animals is both time consuming and logistically difficult. An alternative approach that...

  5. Aspects of juvenile and adolescent environment predict aggression and fear in 12-month-old guide dogs

    Full-text: Available

    | Contributor(s):: Serpell, J. A., Duffy, D. L.

    Maturational changes in behavior, and the possible influence of the puppy-raising environment on behavioral development, were investigated in a total sample of 978 prospective guide dogs belonging to four different breeds/crosses. All dogs belonged to the same guide dog organization, and had...

  6. Protein expression and genetic variability of canine Can f 1 in golden and Labrador retriever service dogs

    Full-text: Available

    | Contributor(s):: Breitenbuecher, C., Belanger, J. M., Levy, K., Mundell, P., Fates, V., Gershony, L., Famula, T. R., Oberbauer, A. M.

    Background: Valued for trainability in diverse tasks, dogs are the primary service animal used to assist individuals with disabilities. Despite their utility, many people in need of service dogs are sensitive to the primary dog allergen, Can f 1, encoded by the Lipocalin 1 gene (LCN1). Several...

  7. "We Always Hurt the Things We Love"—Unnoticed Abuse of Companion Animals

    Full-text: Available

    | Contributor(s):: Bernard E. Rollin

    Despite the fact that companion animals enjoy the status of “members of the family” in contemporary society, there are numerous diseases affecting the longevity of these animals and their quality of life. Some of the most pervasive and damaging problems accrue to pedigreed animals...

  8. Trainability and boldness traits differ between dog breed clusters based on conventional breed categories and genetic relatedness

    | Contributor(s):: Turcsán, Borbála, Kubinyi, Enikő, Miklósi, Ádám

    Modern dog breeding has given rise to more than 400 breeds differing both in morphology and behaviour. Traditionally, kennel clubs have utilized an artificial category system based on the morphological similarity and historical function of each dog breed. Behavioural comparisons at the...

  9. Estimation of genetic parameters for behavior based on results of German Shepherd Dogs in Switzerland

    | Contributor(s):: Meyer, Franziska, Schawalder, Peter, Gaillard, Claude, Dolf, Gaudenz

    The objective of this study was to estimate heritabilities and correlations of seven behavioral traits in German Shepherd Dogs in Switzerland as well as breeding values for this population. Data from 4855 animals having taken the standardized behavior test of the German Shepherd Dog Club of...

  10. Evolution of facial muscle anatomy in dogs

    | Contributor(s):: Kaminski, J., Waller, B. M., Diogo, R., Hartstone-Rose, A., Burrows, A. M.

    Domestication shaped wolves into dogs and transformed both their behavior and their anatomy. Here we show that, in only 33,000 y, domestication transformed the facial muscle anatomy of dogs specifically for facial communication with humans. Based on dissections of dog and wolf heads, we show that...

  11. Behavior and personality analysis in cloned working dog candidates 복제 기능견 후보의 행동과 성격 분석

    Full-text: Available

    | Contributor(s):: Jin Choi

    Cloning specific individuals is the way to produce targeted animals. This makes newborns without surplus animals which should be adapted to new families afterwards or supported by institutions for whole life. Cloning excellent dogs had been started from this point. Many cloned dogs have been...

  12. Preventing skeletal and neurological problems in guide dogs for the blind and other working dogs

    | Contributor(s):: Evans, K. M., Lewis, T. W.

  13. "Genetics and the Social Behavior of the Dog" Revisited: Searching for Genes Relating to Personality in Dogs.

    | Contributor(s):: Enikõ Kubinyi, Mária Sasvári-Székely, Adám Miklósi

  14. Structural variants in genes associated with human Williams-Beuren syndrome underlie stereotypical hypersociability in domestic dogs

    | Contributor(s):: Bridgett M. vonHoldt, Emily Shuldiner, Ilana Janowitz Koch, Rebecca Y. Kartzinel, Andrew Hogan, Lauren Brubaker, Shelby Wanser, Daniel Stahler, Clive D. L. Wynne, Elaine A. Ostrander, Janet S. Sinsheimer, Monique A. R. Udell

    Although considerable progress has been made in understanding the genetic basis of morphologic traits (for example, body size and coat color) in dogs and wolves, the genetic basis of their behavioral divergence is poorly understood. An integrative approach using both behavioral and genetic data...

  15. The Dog: A Domestic Wolf to Communicate with Man: The Aggressiveness of the Dog

    | Contributor(s):: Jean-Mane Giffroy

    On the basis of research in archeozoology and molecular genetics, it is established that the wolf is the main ancestor of the dog and that domestication would have occurred some 14,000 or 15,000 years ago, 5,000 years before the domestication of another species. The place or places of the first...

  16. Genetic components of companion animal behavior

    | Contributor(s):: Jones, Paul, McCune, Sandra, Freund, Lisa S., Esposito, Layla, Gee, Nancy R., McCardle, Peggy

  17. Determining the antiquity of dog origins: canine domestication as a model for the consilience between molecular genetics and archaeology

    | Contributor(s):: Michelle Jeanette Raisor

    Archaeologists have favored a date of 14,000-15,000 years before present (BP) for canine domestication. However, recent studies of mutations in the mitochondrial DNA sequence by molecular geneticists have implied that dogs were domesticated over 100,000 years ago, which has challenged traditional...

  18. The Dog, the Scientist's best friend: Per Jensen at TEDxNorrkoping

    | Contributor(s):: Per Jensen

    This talk deals with the evolution and development of the dog and the basic aspects of dog behavior and its connection to genetics and comparison with human behaviour. A dog can learn to count, and to distinguish verbs from adjectives. It is clear that dogs understand humans much better than has...

  19. Family Dog Project: history and future of the ethological approach to human-dog interaction

    | Contributor(s):: Abdai, J., Miklosi, A.

    Dogs occupy a specific niche in the human social environment. Some authors argued that dogs' social competence show functional similarities in their components (e.g. attachment, rule following) to that of humans due to their long history living in anthropogenic environment if proper socialisation...
