Which kind of surgery? My bulldog Fiona has had both. The less invasive cadivar ACL which torn about 6months later. We knew it was a risk with her weight but opted for it anyway. She then had the metal plate put in. Sounds worse and propably hurt more but we kept her on pain pills. She recovered from the 2nd on much faster and has no problems now. It is hard to part from them for the surgery and then they are so down for a day or two but was i happy with it all after a couple of days. Best wishes to you and you dog.
