Titans leg surgery

My husky Titan escaped on December 21st and we just got him back December 27 he was in a field and he has a broken leg. The vet said time is limited to get this done and we are in aww on how much this is going to cost. I have applied for a pet car card and was only approved for $400.00 and the surgery is $2500.00. With christmas just passing we are not in position financially to pay this out on full in the time needed to be done. My family is very blessed that he made it home so we ask if you could help it would be greatly appreciated.
