The performance of stray dogs (Canis familiaris) living in a shelter on human-guided object-choice tasks

A decade of research on domestic dogs'' responsiveness to human actions has led some to believe that all members of the species Canis familiaris possess a human-like social cognition not shared by their nondomesticated relatives. However, comparative studies on diverse populations of domestic dog are lacking, making species-wide generalizations premature. In this study we present the performance of one under-represented population, stray dogs living in shelters, on a human-guided object-choice task. Unlike pet dogs, shelter dogs universally failed to follow a momentary distal point to a target location in initial tests, although they were able to follow a simpler form of human point on the same task. Furthermore, the majority of subjects learned to follow a momentary distal point to a target when given additional training trials (experiment 2). Dogs'' sensitivity to human gestures may not be entirely explained by phylogenetic variables; rather, the interactions between genetic, developmental and experiential variables must be considered.
