For a delicious, natural chew your pup just can’t put down, try Wild Eats Collagen Retriever Adult Sticks 0.6-cm Duck Flavor Dog Treats. These gnaw-some chews 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. Plus, they come in a fun stick shape! These chews offer a tasty alternative to bully sticks and rawhide treats.
