Rocky needs an operation!!

Rocky was rescued at an abondoned, falling down house after the owner died. He was very timid and it took about 3 weeks for us to make friends. It was clear he had been in some sort of accident and had limited use of his left, back leg. I was able to get him to a vet for shots, and am happy to say he is HW negative and in overall good health. Except the hip. He had a dislocation that has now healed incorrectly. The only option is surgery to get him back his use of the leg. He needs a FHO (Femoral Head Osteoectomy) which will cost $800-$1000.00. I am asking for donations for his care - 100% of donations will be used for Rocky's care. Thank you :)
