    | Contributor(s):: Mohan-Gibbons, H., Weiss, E., Slater, M.

    A survey given to animal shelters across the US reported food bowl guarding as one of the most common reasons for euthanasia and only 34% attempted to modify this guarding behavior. This study identified 96 dogs that guarded their food bowl during an assessment, and then placed them into a home...

  6. Heritability of behavioural traits in domestic dogs: a meta-analysis

    | Contributor(s):: Hradecka, L., Bartos, L., Svobodova, I., Sales, J.

    Reviews summarizing the literature on heritability of behavioural traits in dogs have been published repeatedly over the last four decades. The conclusions of these reviews vary to some extent. We applied meta-analysis and re-evaluated the literature available collecting 48 references dealing...

  7. Investigating the role of coat colour, age, sex, and breed on outcomes for dogs at two animal shelters in the United States

    | Contributor(s):: Svoboda, H. J., Hoffman, C. L.

    The popular press frequently reports that coat colour bias negatively impacts shelter adoption rates for black domestic dogs. This phenomenon, commonly called 'black dog syndrome' (BDS), reportedly increases the likelihood of euthanasia for black dogs and negatively affects the length of black...

  8. Object Neophilia in Domestic Purebred Dogs

    | Contributor(s):: Lydia Kniowski

    Neophilia is defined as a preference for novelty. This characteristic has been described in a variety of animal species, and may have been a contributing factor in the domestication of dogs. This study tested three purebred dog breeds for neophilia with inanimate objects. Observations of...

  9. Are emotionally attached companion animal caregivers conscientious and neurotic? factors that affect the human-companion animal relationship

    | Contributor(s):: Reevy, G. M., Delgado, M. M.

    Few studies have examined how personality traits may be related to the amounts and types of attachments humans have toward companion animals (pets). In this study, 1,098 companion animal guardians (owners) completed a survey that included the Big Five Inventory, the Lexington Attachment to Pets...

  10. Breed differences in everyday behaviour of dogs

    | Contributor(s):: Asp, H. E., Fikse, W. F., Nilsson, K., Strandberg, E.

    The domestication of the dog and the ensuing breed creation has resulted in a plethora of dog breeds that differ not only in morphology but also in terms of behaviour. In addition, a majority of the dogs today are no longer utilized for their working ability, but are mainly kept as companion...

  11. Speed of dog adoption: impact of online photo traits

    | Contributor(s):: Lampe, R., Witte, T. H.

    The Internet has radically changed how dogs are advertised for adoption in the United States. This study was used to investigate how different characteristics in dogs' photos presented online affected the speed of their adoptions, as a proof of concept to encourage more research in this field....

  13. Analysis of the phenotypic link between behavioural traits at mixing and increased long-term social stability in group-housed pigs

    | Contributor(s):: Desire, S., Turner, S. P., D'Eath, R. B., Doeschl-Wilson, A. B., Lewis, C. R. G., Roehe, R.

    Mixing of growing pigs results in aggressive contests between group members. As aggression serves to establish dominance relationships, it is possible that increased initial aggression may facilitate the formation of social hierarchies. The objective of the study was to investigate whether there...

  14. Does temperament affect learning in calves?

    | Contributor(s):: Webb, L. E., Reenen, C. G. van, Jensen, M. B., Schmitt, O., Bokkers, E. A. M.

    The aim of the study was to investigate how temperament affects learning ability in calves.
