Cant afford surgery for my dog -elbow dysplasia

 Hi everyone My 4 year old German Shepherd,  Blue, has 2 broken ribs, a dis-located hip and has 'Grade 7' elbow dysplasia (don't know wha grade 7 means).

He is only 4 yrs old, very fit and healthy (besided the problem listed) but I just can't afford the surgery and medication he needs. Vet said it would cost over £4000 to do the surgery and give all the medication! Is there something else I can do for my darling dog? I have asked the vet for other options - he said surgery was the best option.

He is in so much pain and I hate seeing him like this; he cries when he is in bed. He got ran over by a truck only 3 days ago and the signs of his injuries are showing a LOT!!!

Please Donate generously I dont want to lose my dog :(
