Hi- i am trying to search for anyone who has dealt with and older dog who has bad back legs and how to best help them? I have a 20 pound jack russell, who is 8. He means the world to me. Both his back knees are bad. He has a hard time walking sometimes. Its his ACL, vet says to give him the meds and make him comfortable. Is not recommending outright to do surgery at his age. He is on anti inflamitory meds but i really want to make sure i have the best knowledge on how best to help him. Other than the knee issues he is a great dog and my best friend. Any suggestions would be great. Thank you!
