We have purchased this product from several times for our three labs. Labs, like many other large dogs, may suffer from hip dysplasia and other joint problems. For this reason, we began our labs on a supplement to help with potential joint issues at a very young age. We used to purchase a higher-priced product from a different website. That product has since been discontinued. This product is comparable in ingredients, is highly palatable to our dogs (no nose-turning or walking away from the molasses taste), and seems to provide the benefits of maintaining their joint health. In the two-plus years that we have used this product, our twelve-year old lab has continued to "bounce about" like a puppy and our two six-year olds seem to be faring well. That's all I need to see. We will continue to use this product and to buy it from the site with the most reasonable price for the product.
