I won't compare human intelligence to that of a dog. There have been studies and theories, but bottom line, it is all educated guessing. I mean, why are we breeding them, and caring for them, if they are as intelligent as us, they'd take care of those basics things themselves. That's what they do in the wild, humans have stepped in to harness what they are selecting for.
Jack, I never saw Robert T, heard about the dog, but if he was really that bad M'fer, and had the nasty habits, which I have stated that I personally do not like. I would not breed to that dog. (mangy feet are no issue, that can be cured) There are other bad M'fers I'd be selecting for. Ones that don't destroy everything, I agree it is cunning sometimes the things these dogs do to their environment.
But I would be selecting dogs that are cunning when it counts, when faced with a real problem and ones that think on their feet in a jam. Those are the truly special animals in my book.
