Perspectives on dog human interactions In comparative psychology we draw inferences about the evolution of cognition by investigating the similarities and differences between human and non human animals. I am especially interested in which cognitive skills have evolved in different species that allow them to be optimally adapted to their environment. Dogs due to their high sociality and the fact that they were subject to a special domestication process represent a highly promising model to investigate social cognition from a comparative perspective. Studying dog cognition not only sheds light on the question on what skills humans share with other animal species but also what kind of selection pressures lead to human like skills. Dogs are not simply pets that live in the human environment but they also form a close relationship to humans and cooperate with them. Thus studying dogs living in that special niche will not only inform us about their cognitive skills but might also help us to better understand the selection pressures that led to the unique cognition of humans. In this thesis I present a view on dog cognition that differentiates individual cognitive skills pointing out how exactly they are adapted to their special human environment. Thus I emphasize the unique closeness of the dog human relationship. I also point out where current findings are incomplete or show limits of their paradigms and call for further research. Firstly I criticize the fact that most data on dogs’ understanding of their social and physical environment is based on performance in the visual or sometimes in the auditory modality. As dogs’ olfaction is their most relevant sense I therefore call for more dog studies that are based on olfaction. Secondly regarding the dog human relationship there are many open questions that have not yet been considered well enough: for example whether dogs are capable of skills like empathy the human perspective on dogs and cultural differences in dog human interactions. Thirdly to better understand the dog human bond it is crucial to further investigate when where and how domestication started. This is also needed in order to understand why dogs were domesticated and what made and makes them valuable for humans. To answer the above mentioned questions an interdisciplinary approach is crucial in which scientists from the fields of archaeology linguistics paleoclimatology genetics anatomy ethology psychology sociology and anthropology work together.
