HMMM.....
I did read your post and it does kinda surprise me with a few things....
First, recovery is at least 8 weeks and it is serious. Next, did the Ortho Vet tell you exactly how the surgery was going to go? Is he ONLY deepening the groove? OR is he going to cut and pin? IF he is only deepening the grove, I say NO WAY - NOT WORTH IT - If you are going to put her thru the surgery it should be the cut and pin and also deepening the groove.
LP surgery is not 100% guaranteed. She can slip and injure her knees at any point in her lifetime (before or after surgery).
After going to 2 Ortho Vets, I settled on someone, but I too said I was waiting until the next holiday weekend (which was a good 6 months) so I could have time off to help her recover. Unfortunately Roxy started to limp and carry her leg often, so we did surgery as soon as we could, which was probably about 4 months after her consult.
I would get the Cosequin and start her on that daily. I would monitor her and if she started to limp, etc...that's when I would go for surgery.
My boy TJ has LP as well, probably Grade 1 or 2 - He never limps or carries his leg. Only on occasion do I feel/hear a click in his rear legs. But I will not put him thru a major surgery like that unless he starts to have symptoms or the Vet says it has progressed to Grade 3 or 4.
...not sure if that helped or not
P.S. If you go to Ebay and search for Foam Ramps - you'll find a product that is wonderful to get for her to go up and down from the couch
