These links say pits are not human-aggressive. But they do give you some good information and tips.
I just knew if I got talking about dogs I would want a bigger one then a shih tzu. Anyone know anything about Golden Doddles? I need a non shedding dog and I think they look so cute. The people I have spoken to say they are great with children and very friendly. But they are breeders so I was wondering if anyone knows any or has one.
