Our pup is 9 weeks old (we got him when he was 8) and I have a behavior question. Yesterday morning, while taking him out for potty, he saw someone walking their Husky on the other side of the street. The hair on his back stood up, he growled and then he barked a few times. Is this normal for a dog his age? Other than that, he seems very socialized and is the most loving, cuddly pup (I read in another thread where someone called their Doberman a "velcro dog"...that's our Damon!). We have 2 other smaller dogs and he shows them no aggression at all. The only reason I ask is because many years ago, friends of ours had a young cocker spaniel pup who at a few months, did the same thing, the hair on his back would stand up and he would growl at anyone who wasn't family...he ended up being so aggressive even before he was 1 year old that he bit a small child and our friends had to get rid of him.
