These premium dog treats feature just one ingredient—Icelandic golden redfish—and contain no additives, preservatives or supplements. After being line-caught daily in the icy pure waters of Iceland, the redfish are cleaned and air-dried within FDA, USDA, EU, and MAST standards and regulations. Since these treats feature only one protein source, they are a great choice for dogs with food sensitivities. Plus, they reduce tartar and plaque build-up for healthier teeth and gums.
