Hi, I'm new to this but I just had to write when I read what everyone was writting about. I have an Am Staff and a Pit Mix and I would never be scared of them. When I first picked up my Am Staff (Cali<3) She wasn't very human friendly and my work group had a camping trip, so I thought I would socialize her and took her. She barked at every on and would growl whenever anyone came near. Then she would get use to them and be fine, till they changed. (she wouldn't remember them) But I took her to dog daycares, had people visit and now she loves people. And my pit mix, I just picked her up and she loves people more then any dog I have ever seen. People walk by when I walk her and she just stares and doesnt give up when we walk by. She has to say hi to every one. Bad thing though she was a stray and she has tick fever and demodex so notbody wants to pet her. I feel so bad. When she gets better I want to check into her being a therapy dog. I think she would live to do that!!! Anyway I love Pits, Am Staff, well any dog. There are always a few in every breed that might have a screw loose, but gosh how many people have screws loose? Pits just have the jaw power and teeth. That's all!!!
