My little female is the most people-friendly dog I've had in a long time. She'll let the kids hold her down and blow raspberries on her belly. She does well in public, making friends with folks. Had her 2.5 years and she's never growled at a person.

BUT... she is without a doubt the boss (in her mind) of any other animal that comes around. I live out in the sticks, so it's not too much of an issue here, plus she is not allowed to roam. I'd not really trust her around livestock, other strange/unproven dogs, or any other small animals without being on a leash. I've seen her barrel into three different big male dogs that came around and she's like a guided missile with no "quit", even when they are twice her size. I've said it before, but there's no way I'd want a big pit variant. Too much power and drive for many folks to handle. I have to admire their grit as working dogs, but they are often not worth the potential hassle.....
