oh no!! poor Emma! that sounds horrible, I *hate* when people allow their dogs to run up to other peoples dogs in an on-leash area, whether the dogs are friendly or not, you never know.. its not only irresponsible, its totally rude and careless. I would take Emma to the vet, if you haven't already. Get them to give her a cortizone shot, or clean the area atleast, and give that guy the bill - he HAS to pay it. If he does not, you can legally pursue him, and he will be fined for having his dog off-leash on top of that.

This is why I also don't go to the dog park much anymore... people bring dogs there that are alpha and agressive. Last time we went to this really busy park downtown, uggh.... this girl had a HUGE dane x shepherd mix female, who was being a brat to all of the dogs, and Gonzo was completely being friendly and went up to her with his tail wagging to play, and the dog pinned him down and proceded to bite and mouthe him. I had to pull her off of him (she was atleast 120 lbs!), and she tried to bite me. then, of course, when people came over to ask what happened the dog's owner said "that other dog ran up and growled at her!! she was only defending herself". oh gawd, I hate people like this, that insist they're dogs are angels and refuse to own up to anything. he got 4 punctures, and we made her pay our vet bills and... ugghh.... it just makes me way too mad to even think about it aanyway, I know how you feel, and it's horrible that happened to sweet Emma!! you are totally in the right, and you and your dog deserve payment... hopefully it'll teach the idiot owner a lesson >.<
