Wild Eats® Collagen Bagel Duck Flavored Dog Treats feature beef gelatin, a cooked form of collagen, as the number one ingredient. Collagen supports strong joints and muscles. It also promotes a healthy coat. Wild Eats collagen is hydrolyzed to help break down the dermis layer, making each chew easy to digest. These chews offer a tasty alternative to bully sticks and rawhide treats. Just 23 calories for a long-lasting, guilt-free treat with a unique bagel shape.
