For the past few years, we have been experimenting with different brands of hip and joint supplements for our Beagle/hound mix, Bubby, but her condition has been deteriorating. We tried an anti-inflammatory prescribed by the vet, but it caused her to gain weight and behave differently, so we stopped. We then found Nutrafitz, a higher quality supplement, and after just one week of taking it, we noticed Bubby was more comfortable. After two weeks, the click in her hip had disappeared and after 17 days, we even saw her running with the other two dogs in the yard. We are delighted with the results and will continue to use this product.
