Let me start off by saying I love my dog to death and he is the sweetest, most non-aggressive dog I have ever known. On the other hand, he is really annoying at the dog park. I try to take him to one at least once a week because it seems like he was socialized very well with humans, not so much with dogs, before he came to me. He LOVES playing with other dogs and running around, but the second other dogs start playing rough with one another, he starts barking. Not viciously, but more of a "Hey guys, cut it out!" type bark. And he doesn't stop. I was humiliated last night when other people were dragging their dogs away from him. He went after the one dog that seemed to be the instigator of the rough play and just kept barking at him. His tail was wagging and he wasn't being aggressive and even play bowed.I dragged him into "time out" to try to calm him down and it would work, until another dog instigated rough play. It's almost like he is policing the other dogs into playing nice.
Does anyone else's dog do this? Is there a way to train him not to, aside from stepping in myself and dragging him away? I've tried "quiet" and he pretty much ignores me, but that works at home to get him to stop. I am looking into obedience classes after the holidays, is that something that would help?
