My little girl Lola is almost 2 and she has grade 4 in both knees as well. We just had one of her knees done last week. My vet (also the surgeon) likes to do one at a time. Just like Bruce's mom said she is having to stay crated like all the time except to go outside and eat. It is soo hard I feel terrible about keeping her in there, but I know it is for the best. I decided to go ahead with the surgery, because I could see signs of it bothering here, and my vet said it is better to do it while they are young. That way she will get more out of it, the longer you wait the more athritis (sp?) will get there. It is rather expensive, but too me it was well worth it. I am going to get the other one done, after she recovers from this one. Hope this helps in your decision
