I don't believe what vet's bills can be these days. Sophie, the dog of friends of mine, had to have ACL surgery last week - and it cost over $4000. There's a go fund me page for her here.
She hasn't had an easy life before this, either - they found her in a ditch on the side of I-40 between Durham and Chapel Hill, N.C., when she was just a puppy. She had been beaten badly and left for dead.
I hate people who abandon puppies, kittens, dogs, and cats.
