I have a pit bull/chow mix, and a smooth coat chow, I've had 2 rough coat chows, and a german shepherd/chow mix. I've never had anything but compliments on them. I really believe that it's how the dogs are raised, certain breeds of dogs do need to be "socialized", but it sounds like this one has, so I personally wouldn't have any qualms about the dog. A lot of the dog bites are NOT from the big dogs, but the little ones.
