My dog has a partially torn left ACL. We were trying to manage it. He favored that leg a lot and ended up blowing out his right ACL. His left ACL tear was called a chronic condition. It's been that way for a while and the scar tissue is not enough for him to want to bear all his weight on it. I think that's what caused the right one to blow out.
He is under 50 pounds so we had tightrope surgery done. Above 50 pounds they recommend TPLO. Along with the surgery they injected palates in both his knee and did laser therapy on both knees. His left knee is scheduled for tightrope surgery mid January.
This is day four after surgery and he is walking great on it. Still not wanting to place all his weight on the left leg though. He's a very active dog.

He will always be in my heart.
