help foxy the dog

Two weeks ago we rescued a corgi , Jack Russell cross dog who we named foxy. He is three years old and went in today to be castrated. While having the operation the vets noticed something wrong and phoned me to ask if I would pay for an xray. When I collected him I was so shocked at what I saw. His bone in his leg had partially died and folded over so the top part of the bone is behind the remaining bone. This is obviously why the dog had been abandoned in a dog home. The vet said he will be in alot of pain and will need a specialist operation to prevent any more pain. Costing £1500 Ive already paid out £400 leaving me broke. So foxy would be so grateful if you can help him have his operation as soon as possible
