If you take into account that wolves are incredibly inbred, due to the fact that when a pair wants to set up a pack of their own, they leave the original pack - led by their PARENTS. This means that every wolfpack is severely inbred, but they do not seem to suffer the problems that the domestic dog does. Why?? The reason is that nature does not allow the weaker, diseased wolf to breed the way man does with the dog. We really need to stop humanizing our animals and applying our own mores and standards to them. We need to realise that it is OUR influence that causes the genetic problems in them, because they would choose an entirely different mate in the wild, if they were permitted to breed at all. They do not choose on the basis of conformation, but whether the mate is a good hunter and can stand it's ground in the pack heirarchy. Unfortunately, if these standards were used in the breeding of dogs, none of the breeds would be able to maintain their different appearances and they would all denigrate into a standard pariah-type dog, size and general appearance depending on environmental factors. AND THEY WOULD STILL BE INBRED!!
