Billy ray's acl repair

Hey guys, 

It saddens me to even make a post like this, or even ask for some help. My rescue dog has injuried his anterior cruciate ligament (acl/knee) and needs surgery as soon as possible in order to reduce the chance of arthritis or further damage since he's so young.

Unfortunately, the vet also said his opposite knee that is injured is showing signs of a acl tear so he will most likely need two knee replacement :( 

If you know Billy Ray, you know hes the most laid back, caring and compassionate dog and he deserves to live a long happy life but since his injury it stops him from being able to enjoy life and be a puppy dog. He has brought so much joy to my life and everyone around him and I want to give him the world..

Due to my financial situation at the moment I'm unable to pay in full for his surgery, let alone both of them and it's not cheap! It's suggested to do one knee at a time and recovery is a long road for my poor baby.
