so, my dog got into a scuffle with another dog yesterday at the park and it wasn't pretty. Everything was going fine at first. My wife and I had been there for about an hour at this point and our dog was playing with the other dogs and just doing his own thing. From out of nowhere another dog comes along and is behaving in an aggressive manner toward our dog. The other dog started chasing him and then proceeded to snarl, bark and nip at him while he was trying to get away. At one point this dog caused him to stumble and yelp. The next thing you know, a full blown fight breaks out between my dog and the other dog and all hell breaks loose. I've owned George for 7 months now and he's never gotten into a fight like this. He's been harrassed plenty of times by other dogs at the park but he's never fought back. When it was all said and done I jumped in and grabbed George by his collar. I saw the owner of the other dog leashing her dog up about 10-15 ft away and I saw that he was bleeding. I asked her if her dog was ok and she said yes and that his nose was bleeding. So basically my dog got him pretty good while our dog came out unscathed. Despite the other dog being the aggressor (in my opinion) I still felt bad that he was hurt. On the other hand, I also felt the onus was on the other dog owner for bringing her aggressive dog to the park. My dog stood his ground and when he was further provoked he fought back.So my question is, what would you have done? Would you assume financial responsibility for the injuries the other dog sustained? Or is it the other dog owner's fault for allowing it to escalate? I know I could've stepped in and pulled my dog out at the first sign, but like I said, in the past these other aggressive dogs usually went away or I would step in and pull my dog away. The other owner simply leashed her dog and left and that was the end of it. What would you do? Am I wrong in thinking that my dog did nothing wrong?
