Help for Bones cruciate ligament repairs

On February 28 Bones had what seemed like a minor fall. His vet diagnosed him with a torn cruciate ligament in his back left leg. He will need surgery to repair his leg, if he is eligible due to his Cushing's, elevated liver enzymes, and his age. It can be quite expensive so we are asking for a bit of help to cover the costs of surgery, pt, leg brace, water therapy, and lazer treatments.  Any little bit helps.  Bones is a very good boy, he is such a sweet little dog, I hate to see him in this condition. He is always full of life and energy. Hopefully once he has his treatments he will be on a speedy road to recovery. Thank you so much in advance for anything you can contribute.
