Despite our close relationship, communication between dogs and people has serious limitations. We can only communicate with each other in a very weak approximation of the full depth of either of our languages. Despite our attempts at clarity, there is so much lost in the translation, and it’s not even always obvious whether an action is meant to be communicative. I do believe that love and friendship can be expressed and understood quite well, but less important details can be more confusing to members of both species.
