Sorry to hear about your pup, hope he has a full recovery. There's a lot of this going around right now, two weeks ago a dog was killed at our local dog park. Owner fled and left his dog at the park, by-law caught the dog but not the owner. Might want to look in to "vet insurance", for about $35/month they will cover anything up to $20,000/year I think? I broke down and got this two months ago knowing that if something happens to my dogs I'll go broke and pay the bill before I put them down.
