Save my boy

Here's an update - Sir now has full bone coverage, his tendon has reconnected and we expect full recovery!!he has a long way to go- we still need help paying the vet bill, it is about $15,000 now. thanks to all that have helped so far---- anything you can do helps. thank you so much- he's13 yrs old. He has cut both back legs,one to the bone and severed his extender tendon. He has a long road to recovery any help is appreciated. thank you
