Welcome to YT. Well, if she isn't limping and it's no higher than a grade 3, I wouldn't be so quick to let a regular Vet. do the surgery. My Zada had a grade 3, wasn't limping but yet I put my trust in my regular Vet. who did the surgery. He didn't even deepen the groove. I took her to an orthopedic surgeon who said she should not have had the surgery since she wasn't having any pain. She had a torn ligament and he did the surgery. This is how he found out about the LP surgery. I had him check Azrael and he said she had a grade 3, but didn't recommend surgery unless she is having pain/limping. She's 6 years old and still not bothered, and may never have problems. So be extra careful about rushing into surgery. Have a board certified orthopedic surgeon check her over.
