Not only are they delicious for your dog, but they also reduce tartar and plaque build-up for healthier gums and teeth. They are also a great natural source of Omega-3 & Omega-6 fatty acids, promoting healthy skin and coat for your pet. With just one ingredient, these tasty and healthy treats are perfect for dogs with protein sensitivities. Our natural and edible fishproductsoffer peace of mind, as they are cleaned and air-dried within FDA, USDA, EU, and MAST standards and regulations.
