In 1972 a small family owned butcher shop called Detroit Processing Inc was founded. As the business grew in 1992 they started Texas Tripe and have been manufacturing raw pet food products. Texas Tripe never uses any hormone or antibiotics. All their ingredients are sourced in the USA from USDA inspected process. All the meats used are premium grass feed beef, grass fed green tripe, premium pork, all natural unenhanced chicken and turkey. Most of their blends are 80/10/10 formula with no added ingredients. Straight from the farm to your pets bowl.
