* 100% Pure * No Fillers The Need: Humans are not the only species to suffer joint problems. Dogs, cats, and even horses, as they age are subject to many of the same joint afflictions. Inbreeding of these animals has caused the traits for hip displeasure and joint deterioration to dominate many of the breeds. Animas can suffer more than humans without showing any symptoms. "Pack animals" such as dogs, for example, have a genetic instinct developed over thousands of years not to show weakness, illness or pain so that the other members of their pack do not attack them or leave them behind. It is a basic survival instinct. Since 1993 Seagate shark cartilage has been recommended for these animals. The Source: Seagate processes this shark cartilage using the identical freeze-drying process and quality controls as their shark cartilage for human consumption. Shark Cartilage is composed of 90% chondroitin sulfate that is naturally contained within a complex protein molecule linked with the minerals calcium and phosphorus. When you (or your pet) swallow the shark cartilage, the digestion process (hydrolysis) splits this complex molecule in the presence of water and acid in the stomach, and the chondroitin sulfate is released. Chondroitin sulfate is an important component of bones, cartilage and connective tissue.
