Amazing! Instead of the vet tech moving the infra red laser above Logan's hips and back, today she used a massage attachment on it and used it ON her skin for more penetration. It looked so good! (me next!) Logabeans didn't shake or anything, just was a bit impatient towards the end. I'm still in awe of the miracles of science for our pets that were non existent just years ago. I remember we had a puppy when I was around 7 and he broke his leg. It didn't heal so he was pts. Today there's specialists for everything. Yay!
