Green Tripe is our cornerstone. Green Tripe has been central to PetKind since we began producing dog food in 2001. We know the amazing impact of this nutrient-rich ingredient on the lives of the animals we cherish, so we set out to ensure Green Tripe was the leading ingredient in all TRIPE DRY recipes. We use Bison, Beef, & Lamb Tripe throughout the 4 formulation line-up, all sourced from top quality suppliers and CFIA approved for human edible consumption. We wouldn't have it any other way.
