Okay so I got this pup she's around 15 weeks or so old, she didn't come from the greatest situation, I know her father is aggressive, not sure about her mom. She growls if she feels scared or something, growls in the crate, bites my hands, if I try to grab her collar if she chews on the rug or something she goes to bite my hand. I'm at a loss here. I've never owned a puppy before let alone a pit puppy. I don't know what else to do. My dad isn't going to stand for all this and my mom doesn't know what to do either. Any ideas on what could help?
