Please, try to talk to some other vets to see what, any options you have before putting him to sleep. I'm sure you will find someone who has seen something similar enough to what's going on with him that they think some treatment is worth trying. At the very least an x-ray might tell something and a pet x-ray is not very expensive. We can help you with at least $1100 now, I don't know if anyone can get you more but have you asked your friends and family to see if they can give you any money for this?
