Cod doughnuts are made from air dried cod skin, naturally rich in omega 3 and high in protein while staying low in fat. Omega 3 is a natural support for healthy skin and coat, and the slightly abrasive texture helps clean teeth as your dog chews. A soft, single protein fish chew, so a good option for dogs with sensitivities or those new to natural chews. An air dried cod skin, formed into a doughnut shape, this is a gentle, fishy chew that dogs go mad for. Beth, one of our IMDT qualified trainers, likes these as a lighter treat that's naturally rich in omega 3, and a good gentle option for smaller dogs, puppies and seniors alike. The ring shape gives a bit more to work at than a flat piece, while still being soft and easy going. Suits all sizes.
