Hi Lills Mum
Robbie had had both his knees done before he was 12month's, it was only his left at first and it was decided to see how it went before opperating but when the secound was showing problems we had the left done and then a few month,s later the right.
It certainly has improved his mobility before he would not run but more of a hop and skip and often stop when his knee had poped out. The opps went well no probs and both time back to normal within a week. As for the arthritis if he should get it there are herbal tablets if you do not want medication.
But go with what your vet say's if it is not to bad hold of I really had no choice with Rob. Hope this helps
