My Ollie had it done with a laser by an orthopedic surgeon. He was under getting his broken elbow fixed and a neuter so needless to say he was quite sore. But he did heal quickly. The laser was definitely the way to go. I'm glad your little one is better! No differences that I have seen. Snores a little and he did throw up a couple times after surgery. But he's all good now. That was about 7 weeks ago that he had surgery.
