Strange thing happened to my pup today. The weather was fairly bad today and there wasn't many dogs at the local dog park where I take her to run. So, a new person comes along with his black lab. Seems fine. The lab was wanting to play with my dog. Both tails were wagging, running, playing then 5 minutes into it all of a sudden the lab turned vicious. Teeth flashed, growling, the lab pinned my dog down. My dog was welping and also flashed teeth trying to get free. This was definitely notplay fighting. I had trouble pulling the lab free. The ownerfinally pulled his dog free and he leashed it but still wanted to get at my dog with his tail wagging!

My dog doesn't have dominant bone in her body. Every other aggressive dog gets along fine with her. But this is the strangest behavior I've seen in a male dog. Could it be owner abuse or dog has psychological problems?
