My 12 year old, 85 pound Great Pyrenees has hip dysplasia and arthritis, and she was really suffering even though she was on Galliprant and Gabapentin medications. I was thinking I was going to have to put her down but saw this product, read the reviews, and took a chance. I figured I didn’t have much to lose. The product arrived quickly and I got her on it right away. She was showing improvement in a couple of days! Because I recalled a reviewer writing that long-term improvements would be the case, I ordered the three-bottle-pack. She just finished up the first bottle and the improvement is nothing short of remarkable. I will have her on this product for the rest of her life.
