Dogswell Happy Hips Salmon Jerky helps your pet maintain healthy hips and joints with Glucosamine and Chondroitin. Dogswell has recently added small amounts of wild-caught Whitefish to the formula to add more variety to the flavor profile and improve appetite appeal. Whitefish, like salmon, is rich in omega 3 essential fatty acids, which contain DHA, a good source for healthy growth development. It is low in fat, high in protein and a good alternative for pets with allergies and sensitive stomachs. Vitamin E is an antioxidant rich essential fat soluble vitamin. Vitamin E keeps the connective tissues strong and prevents skin and muscles from losing elasticity.
