I am so sorry to hear about Casper. What a scary experience. I hope he has a speedy & full recovery.

I am the owner of a Rottweiler who can be dog agressive at times. She is ALWAYS under my control and supervision. I do everything in my power to keep her & other dogs safe and so far knock on wood do a great job at it. But do know I would be devastated if she attacked someones dog, but I would be even more devested if she honestly got loose by accident (accidents do happen unfortunatly) and animal control took her away from me. That is as long I showed genuine concern & offered to help with vet bills and the like (which is what I would do).

Seeing as he was concerned and came over immediately, as long as he is willing to pay for the vet bills I would not get animal control involved. I would however warn him that if there is a next time animal control will be involved.

Personally I would ask the owner to reimburse me for ALL the vet bills if your dog WAS on a leash. If your dog was NOT on a leash though I would only ask to be reimbursed for part of the bills (no more than half even if your dog did not enter his property or cause problems)
