I’m so incredibly happy at the results from just 1 months use(2 pumps per day). My bulldog couldn’t sit comfortably because of a very sore knee joint, he would get up barely putting weight on it and had a constant limp. Decided to try this and within a few weeks, I noticed no more limp, putting full weight on his back leg, sitting comfortably again. He now has his daily “zoomies” crazy run in the backyard jumping up & down, rounding the trees and how much easier he’s going up & downstairs. No doubt this product is the reason why. It’s such a small price to pay to keep your best friend healthy, happy and mostly pain-free! They’ve got a customer for life!
