This product has made an amazing change in my old dog, who is 10-1/2 yrs old and is a giant breed (Black Russian Terrier). He has had loss of mobility for a few years now. Our groomer recommended this product, and he is now able to jump on the bed (he’s allowed!) and the futon, which he hasn’t done for a year till now. He is less sore, moving around, getting up and lying down. Highly recommend this to all dog owners, especially large or giant breeds!
