    The welfare of animals in captivity is of considerable societal concern. A major source of stress, especially for wild animals, is the lack of control over their environment, which includes not being able to avoid contact with human beings. Paradoxically, some studies have shown that...

  9. Evaluation of effects of olfactory and auditory stimulation on separation anxiety by salivary cortisol measurement in dogs

    Journal Articles | Contributor(s): Diane Lefebvre, Claire Diederich, Madeleine Delcourt, Jean-Marie Giffroy

    Separation anxiety (SA) is a serious behavioral problem in dogs. In this study, salivary cortisol was studied to determine if the owner's odor or voice could reduce SA in dogs. Twenty-eight dogs with SA were divided into three groups: group 1 (control), group 2 (with owner's clothes...

Understanding the prevalence of diseases, in relation to age and breed, would support appropriate guidance for future health care strategies and provide useful information...

  11. Dogs (Canis familiaris), but Not Chimpanzees (Pan troglodytes), Understand Imperative Pointing

    Journal Articles | Contributor(s): Diane Lefebvre, Claire Diederich, Madeleine Delcourt, Jean-Marie Giffroy

    Chimpanzees routinely follow the gaze of humans to outside targets. However, in most studies using object choice they fail to use communicative gestures (e.g. pointing) to find hidden food. Chimpanzees' failure to do this may be due to several difficulties with this paradigm. They may, for...
