This study specifically focused on Labrador Retrievers, consistently one of the most popular breeds both...

  2. Canine scent detection—Fact or fiction?

    Contributor(s):: Johnen, Dorothea, Heuwieser, Wolfgang, Fischer-Tenhagen, Carola

    Dogs have been used in a variety of scent detection tasks for hundreds of years. However, methodological differences in the design of studies concerning canine scent detection make it difficult to directly compare and to evaluate their results. We set out to (1) evaluate the quality and...

The current study aimed to further assess the impact of homing age on these behaviours in adult dogs. Finnish dogs provide an interesting population for this further study, as...

  8. Do shelter dogs engage in social referencing with their caregiver in an approach paradigm? An exploratory study

    Contributor(s):: Duranton, Charlotte, Bedossa, Thierry, Gaunet, Florence

    When confronted with an unfamiliar object or person, privately owned pet dogs engage in social referencing, synchronizing their reaction with that of their owners. The question of whether shelter dogs do so when confronted with a stranger has not yet been studied. We tested the reactions of 30...

  9. Qualitative Behaviour Assessment of dogs in the shelter and home environment and relationship with quantitative behaviour assessment and physiological responses

    Contributor(s):: Walker, Jessica K., Dale, Arnja R., D’Eath, Richard B., Wemelsfelder, Françoise

    Qualitative Behaviour Assessment (QBA) was utilised to examine the behavioural expression of dogs in different housing environments and the results were compared to measurements of quantitative behaviour and physiology. Firstly, quantitative behavioural and physiological differences were...

  10. Performance of domestic dogs on an olfactory discrimination of a homologous series of alcohols

    Contributor(s):: Hall, Nathaniel J., Collada, Adriana, Smith, David W., Wynne, Clive D. L.

    Dogs are deployed for the detection of a wide variety of chemical stimuli. Despite their wide use, little basic research has explored canine olfactory generalization and discrimination. In the present study, we assessed canine odor discrimination amongst a series of chemically-related aliphatic...

  11. Negative effects of epilepsy and antiepileptic drugs on the trainability of dogs with naturally occurring idiopathic epilepsy

    Contributor(s):: Packer, Rowena M. A., McGreevy, Paul D., Pergande, Amy, Volk, Holger A.

    Epilepsy and anti-epileptic drug (AED) treatment have been found to induce or exacerbate underlying cognitive impairments in people, affecting learning ability, attention and memory. Idiopathic epilepsy (IE) is the most common chronic neurological condition in dogs. Whether IE impairs cognition,...

  12. Canine Aggression: Understanding Owner Beliefs about the Biological Locus of Origin for Rehabilitation of Aggressive Behavior

    Full-text: Available

    | Contributor(s):: Destiny DeHart

    The topic of canine aggression– threatening or hostile behavior involving actual and or potential harm to another – invokes many emotional responses due to the often violent connotations regarding aggressive canines. Research focusing on various methods of rehabilitation has...

  13. Overweight and obese pet owners: respondent and pet characteristics in the rural Midwestern United States

    | Contributor(s):: Heuberger, R. A., Garner, J. A., Corby, A., DeWitt, K., Sluis, R. vander

    The obesity epidemic has impacted both people and pets in the rural Midwestern United States (MWUS). Tailoring health advice to the socio-demographic characteristics and dietary patterns of owners and their pets can help promote adherence to health behavior changes for owners and foster health...

  14. Online videos indicate human and dog behaviour preceding dog bites and the context in which bites occur

    | Contributor(s):: Sara C. Owczarczak-Garstecka, Francine Watkins, Rob Christley, Carri Westgarth

    YouTube videos of dog bites present an unexplored opportunity to observe dog bites directly. We recorded the context of bites, bite severity, victim and dog characteristics for 143 videos and for 56 videos we coded human and dog behaviour before the bite. Perceived bite severity was derived...
