biting on neck part II/dominance or aggression?
I posted earlier about my dog biting other dogs on the neck and received some good replies, but am worried the problem is growing worse. I've had my dog for almost 2 months, and I think she's a little over a year. She loves to play and wrestle with other dogs, which I think she initiates by biting on the neck, but at times she becomes obsessive with this biting. Yesterday a smaller dog was new to the park and had quickly submitted to some other dogs (not her) and was on his back, and she came over and bit him on the neck! I gave her a time out, and thought she was okay (though in retrospect I should have taken her home), but a few minites later she ended up chasing after another new dog that came in, who was very timid and afraid, and biting him (or her?) on the neck. This other dog was already scared and that made it worse. I took her right home after that. Additionally, she has some friend she plays with quite often, but even after these other dog grows bored of playing, she persists in biting them on the neck. My thinking is that this is how she asserts her dominance over other dogs. She loves playing with other dogs and I don't want to take that away from her, but if this behavior escalates I don't know what else I can do. Is there any way to get her to stop this, or do you think it's turning into aggression?
