The most commonly used experimental paradigm is the object-choice task in which a dog is given a choice of two containers and guided to the reinforced object by human pointing gestures. We review here studies of this type and attempt a meta-analysis of the available data. In the meta-analysis breeds of dogs were grouped into the eight categories of the American Kennel Club, and into four clusters identified by Parker and Ostrander [Parker, H.G., Ostrander, E.A., 2005. Canine genomics and genetics: running with the pack. PLoS Genet. 1, 507-513] on the basis of a genetic analysis. No differences in performance between breeds categorized in either fashion were identified. Rather, all dog breeds appear to be similarly and highly successful in following human points to locate desired food. We suggest this result could be due to the paucity of data available in published studies, and the restricted range of breeds tested.

Due to the success of dogs on perspective-taking tasks, some have hypothesized that domestic dogs may have theory of mind, or the ability to infer what other individuals know. Here we provide the first evidence that nondomesticated canids, grey wolves (Canis lupus), are also sensitive to human attentional state under some conditions. We also demonstrate that dogs do not display an undifferentiated sensitivity to all visual cues of attentional state. Rather, dogs are more sensitive to stimuli encountered in their home environment. Some dogs perform poorly on perspective-taking tasks. These findings have important implications for the interpretation of research designed to understand complex social cognition across species.

Any successful attempt to manage these problems will require an understanding of the mechanisms that control these behaviors. However, for some of the behavioral problems sited, such as jumping up on people, available treatments are not prescribed until after a systematic assessment of the environmental contingencies contributing to the behavior. The current study assesses the use of functional analysis, an established technique for identifying the variables controlling problem behavior in humans, to determine the environmental factors supporting the behavior of jumping up on people in dogs. Statistically significant differences were found in the rate of jumping up behavior across conditions for each dog in the assessment phase. Treatment conditions used the maintaining variable found in the assessment phase. By comparing the rates of jumping up behavior in these conditions, we found the rates to be of lower statistical significance in the treatment condition. Therefore, results show that this methodology is effective in determining the maintaining variables for these individuals, leading to a more precise treatment.
