I'm sorry to hear that, sounds nasty I hope it heals well. i suppose if the dog came bounding over to yours and bit it, then I'd say it's the other dog owners fault. But in this instance yours went over to it, interrupted their game and got a bite. I don't think the other owner can be held that responsible. I think perhaps you needed to be more careful, I know that's going to be hard to hear, but one could argue you didn't have your dog under control. I don't mean to cause annoyance, just pointing out another view.
