I have a 7 year old female (Gracie). Just found out today she tore her ACL in her hind leg. I have done a TON of research online today and all I have seen is that the traditional surgery doesn't last long in large breeds. She already has severe arthritis in her front shoulders. So before this mishap, she had a hard time getting around. I am at a loss as if I do the surgery or not. She weighs 210! So that is a factor also. Any advice would be appreciated! Thanks.
