Watching my dogs run at the kennels where I work, it is often amusing to see who "takes their fancy" so to speak. The dogs in being boarded are behind fences in play yards, and my dogs have the run of the compond around all yards- meaning they can greet the "inmates" but they dont actually have any interaction (for obvious reasons) beyond a through the fence greeting.
If there is a Dobermann there, or even more than one in separate play yards, they will return to him or her over and over and over. They say "Hi" to the other dogs, but a Dobermann holds their attention like no other breed.
Each dog breed I have owned has displayed this type of "breed recognition" behaviour to quite an extent.... So, given I am pretty sure dogs do NOT recognise themselves in mirrors, and given that I'm quite sure my dogs dont use a mirror regularly, what explains this phenomenon?
A friend and I have come up with a theory, but before I put it here, so as not to quell creative genius (!!!), do others have theories?
