Collagen is a Natural supplement that helps to lubricate and protect connective tissues that support the hips and joint health. Think of collagen as the glue holding the contents of the body together. About one-third of the protein in your dog & cat's body is collagen. As your pet's body ages, collagen production slows down, so it is essential to ensure they get enough in their diet. Collagen also is what gives your pet's skin healthy elasticity. A sufficient amount in their diet can help your dog or cat shed less, itch less, and have a softer, shinier coat. May help maintain strong bones, joints, teeth, skin & coat.
