Help Rex raise money for surgery on back legs

My German Shepherd pup Rex is currently only 7 years old. He’s one of the most playful, friendly, loyal, and caring dogs you will ever meet and he needs help. Along with a not very common bone disease, Rex has torn his ACL very badly in his right and some in his left hind legs. Surgery is required for him to be able to get better and only one side of it will cost a minimum of $4,500. We need to get both sides done. We are asking for any donations that could help, Rex means the absolute world to us and has been there through so much of our life. We don’t want him to be in pain or lose him prematurely. Rex deserves a long and pain-free life and we ask that if you are able to donate or simply share this or pray for Rex, please do. 
Thank you all so so much, 
The family who adores Rex to no end.
