He had been playing a little too hard and started limping. After a few visits to the vet, Bones found out Stanley has a fully torn ACL in one leg and a half torn ACL in the other leg. He found out that Stanley wouldn't be able to play for 2 months in his recovery from surgery, and he'd always have to be on a leash to keep him from too much activity. So Bones has been nervous to get the surgery done since Stanley is a very active dog.
However, he shared an update today (October 4) that they scheduled his ACL surgery for next week. Bones is still nervous, but after hearing from vets, he decided it was best for Stanley.
