My 3 month APBT always bites me. This usuallly occurs when she gets really excited and starts to jump around and bite me every were. Sometimes she bites hard which bothers me since she is going to get older. I dont no if she just wants to play rough or she has a problem. Cali is a very good dog and she is well displined listens to my commands usually, but she improves every day. I am socializing her much as possible with everyone including relatives, kids and my friends. She loves other people and she is really friendly with other dogs but afraid of big ones, which causes her to run away. Do you guys beleive this is rough play or a problem and do you guys think it will be a bigger problem in the future? Anyway to correct this problem or is it just normal?
