Oh I see. I am doing exactly the same thing with my 12 weeks old, and just started her puppy classes last week. My previous dog was so agressive with people, kids, dogs, etc., it made life pretty hard at times. I prefer to raise my new female to be friendly, and test her personal protection abilities when she reaches 18 months. Have you tested your dog in PP yet? I want her to be well balanced and behave with great manners, but she'll also need to be agressive if and when needed. Hope she'll turn out that way, but for now, it's puppy time...)))
