My female Cane Corso tore her ACL at 6 month's, broke my heart she was so young! Long and the short of it, she got the surgery, i got her in 5 days later ( wasn't sure what the problem was, wasn't going to rush her to the vet if all she needed was a few days rest). Got the surgery that day. She stayed at the vet the first 5 days. Those are the most important days, they are most unstable on that knee the first 5 days. When I picked her up, she could walk on it well, and knew how to get around with that knee. All was much safer. Of course, I cried everyday that she was gone, but was happy in the end that I did that. I don't remember the name of the surgery, but it was the one with the fish line, not the one where there are plates and screws. KNOCK ON WOOD, over a year later, my dog has not limped, NOT ONCE on that leg. She is a very active dog, she dock dives, goes hiking, goes running, and is going to compete in IPO. My vet swore up and down that she would have flare ups as she got back into activity, nope not one. My vet says her success is uncommon, I'm thinking i's mostly due to her young age at the time of surgery, she probably just bounced back quicker hen an older dog would. I also swam her that summer, that helped a lot I think. My next CC, will be in the pool by 5 month's, Cianna tore her ACL while running too hard. They are sstill gangly and unstable, more chance for injury while running full tilt especially when they are still gangly and awkward haha. Anyway, because of her injury, and because of the chance she could blow her other knee, I am careful with her. I don't let her play with dogs often at all, and I make sure she has at least 3 days a week with no strenuous activity. Other then that, her life is completely normal now. I have also heard of others iwht good success with the surgery. Good luck!
