I recently just got a puppy, Callie, last week and she was 11 wks old when I got her. She was fine for the first few days that we had, really loveable and everything however in the past day or two she has started to get more aggressive. She has started to bite pretty hard on hands and feet of us and when we try and get her to stop or say "no" and hold her away from us she begins to growl and if we let her go to walk away she runs at us and tries to bite our ankles or toes. At first when I heard about it (I wasn't home when she started it) I had thought that it was playing or just her mouthing because shes started to get close to the time when she'll begin to lose her teeth. However when I saw her do it, it really seemed like she wasn't playing and that it could've been aggressive behavior.

I've ever something different from a lot of people on how to fix this behavior from grabbing her snout and pushing her to the ground to submit to you, to saying "ouch" and walking away, or even putting coins in a can and shaking it when she begins to act like this. I don't know which of these ways is the best to correct this behavior and I'm worried that it this behavior continues my parents won't want to keep her.

I don't think shes doing it because of lack of socialization, there are plenty of dogs in my neighborhood and she usually gets to play with one or two of them a day. I realize that this is something that probably gets posted a lot but I want to know if shes just slightly more aggressive because she doesn't know her place yet or if there might be the chance that there is something else wrong or if it could be in the breeding.

I hope that you can answer my questions!! I really love my puppy and I would hate for something to be terribly wrong with her...
