My puppy is 11 weeks old now and she is really mouthy. This is my first dog and I have done a lot of research, but it's always different when you actually have one! I don't think she is teething, and I know that they are naturally mouthy sometimes, but I'm getting really nervous for when she loses her teeth and actually gets her adult teeth which I expect to be razor sharp. I don't think she is being aggressive, but I don't think she is always playing around either - it's kind of a mix of both.. I have tried to tell her NO! in a loud voice, I have tried yelping like a hurt puppy, I have tried putting her back in her crate, giving her the right toys for her to chew instead, but it won't stop! And it's usually only me, especially when I am on the grass with her and my feet or legs/ankles are exposed. She snaps at my hands too. Is this normal? What else should I try to do? I don't have the money to afford obedience classes, and plus, I kind of want to be able to train her myself. Any advice? Thanks!
