Simon really is a great looking dog. Such a kissable little face there.
Yeah, like divingbiker said, the recovery is long and hard on both of you. I carried my dog around for quite a while and would stand out there with her and hold the leg up so she could do her thing. The pityful looks I used to get from her would break my heart. (don't let the other dogs see me like this kinda looks ) I also built a ramp for her off the deck next to the steps and she actually liked to use it. I left it there so that she didn't rip those knees out again. I put grip strips on it too so she had better traction when it was wet out.
It was much harder on her than it was on me but she recovered very well and could run and jump almost as well as before the surgeries.

Good luck. Keep us posted.
