Quite honestly, dog “pack” behaviors and “social rank” have become a politically incorrect topic to even discuss. There are many people that believe that dogs are no longer “pack animals” because of domestication. Dogs DO understand “social rank”. ALL mammals understand social rank, meaning that there are those higher in social rank than others. Our human gut reaction is to discredit social rank because we want our dogs to be equals or more human like. We treat them just like we treat our children going even as far as to call them “fur babies” or “fur kids”. If we have more than one dog, they all have the same beds, same collars, and we would never considering taking one dog on a walk without the other! We treat them almost as many people treat twin babies, dressing them the same, and so on.
