I know the original post is from last summer, but I've gotta add that a dog is not only how it was breed, but also how it was raised. We have an American Pit mix (the dad was a purebred AKC registered pit). She is a great dog! She is not animal or people aggressive. We take her out in public (hiking, Petsmart, camping, etc) and she thinks everyone is her friend. She has been with infants and she is wonderful. In fact, we had an infant in one of those baby walkers and Casey (the pit) laid her head on the tray of the walker and let the baby yank on her ears, etc. Of all of out dogs she the most friendly and the one I trust the most with other dogs and children. Casey cuddles with the cat and the chicken free range in our backyard with the dogs. NEVER had a problem. My Brittany/Border Collie mix is the one that would be aggressive before the rest of our dogs since she is scared of everything. It is largely how a dog is raised!
