My female cc has been shy and scared since the 2nd day we brought her home. She was 10weeks old. We started socializing her every day since. Having her meet many new people, dogs and cats. Putting her in different situations to build self confidence(stairs, dark rooms, loud places etc) At almost 12 weeks she started growling randomly at New people and people she had met before many times. I contacted breeder concerned about behavior I was told she was the most out going puppy from the litter and she hasn't had a puppy act that way. I asked her to call me when she started her training classes never got a message so I do I n d a different trainer. We have been in training for the last 7 weeks and my trainer told me she is high risk and I should return her to breeder before she bites someone. She has never growled at me or my 2 girls ages 4 and 6. She is the biggest sweetheart if it is just us. I am not ready to give up yet I am trying to find a trainer that specializes with cc. My goal is to hopefully get her to change her temperament so I can bring her anywhere and not worry if she is going to start growling and take a chance of someone getting bit. Any other tips or suggestions or since she started this behavior so young there is no chance for her to change. <br>
