They wanted to do ACL surgery on our dog for about $2500., some people told us he might favor it and then you will have to do the other leg.
Friend suggested Absorbine Horse liniment, rubbed area twice a day.
He was fine after a few weeks.

Hubby and I use it when we get sore spots, works great.
Have recommended to others with sore limbs, can’t thank us enough.
I use that on my ankle. She hates the smell but I might try it on her kneecap. I doubt she’ll lick it. 😁
Thanks for posting this! Facing the same thing with our dog, and we were quoted as much. Friends told us a custom leg brace works too, but we worry about stressing he other leg. Will try the Absorbine.
