According to their website, the pup hasn't seen a vet yet. So they probably can't make a definite call about the surgery at this time. OP, is this your boy?

It's just a terrible situation. I can only imagine how difficult it was to sign the papers to surrender. Then to realize that the a solution was only hours too late. I wish the OP & the sweet puppy the best.
