I have a 6 year old mixed breed dog - about 90 lbs. He is typcally fine with other dogs. He will either play briefly or sniff and wander off. I have noticed however, that when he comes in contact with an overly submissive dog, he wants to go after them. Today at the dog park he was fine until two approximately 1 year old pit bull females came in. They were friendly but very shy & when my dog went over to sniff, one of them rolled over on her back with her tail between her legs. This seemed to set him off. He growled, lunged and he pinned her to the ground. No one was hurt, but it looked a bit scary. Any ideas what the reaction is about and what the proper response should be on my part?
Your dog is obviously a very dominant dog. We have a nine month old lab thats like that, and she is going to get hers good one day. Submissive dogs can be afraid and fear leads to fear biting. When your dog gets up on his high horse YOU need to roll him. Flip him onto his back and lean on him, use your hand to grab his neck (like wolves do when showing dominance) emulating a bite. He is not the alpha, you are. If your dog takes advantage of someone elses submission, roll him and let the other dog come check him out. Once he realizes that he is not the leader of the pack, his attitude may change. Overly dominant dogs can lead to big problems. Show him his place now.
