I didn't. I called "rank" and "divinity" abstract concepts. Pay attention. Dogs do evidence behaviour that appears subservient, but that does not necessitate they hold or understand abstract concepts such as "rank" or "superiority", does it? Do you think the dog is weighing in his mind all the parameters affecting his relationship with his owner before "deciding" to act subservient or not? Do dogs understand the concept of "superiority" and "divinity" such that they can make a determination that an individual it interacts with belongs in one group, but not the other? Do you have evidence for that?
