Completely Boxer Crazy
Our Dane X did both his ACLs (apparently once they do one the chances of doing the other are pretty high). We tried to keep him from running and jumping and he went really pretty well for 2 years. His legs did start to go out from under him increasingly for the last 6 months, but I suspect that was as much to do with very advanced age as his ACLs and also being 50+kg. If you can keep his weight down and keep him from doing crazy Boxer stuff hopefully he should be OK long term. The vet put Thor on Firocoxib (Previcox) which cost an fortune but as far as I could see he really didn't appear to be in any pain so I think it was really worth it (lucky insurance paid 80%). Best wishes to Waldo and hopefully a nice rest and restricted movement will do him a power of good.
