Wholesome Hide is the only U.S. rawhide company that makes 100 percent of its products in the U.S.A. with U.S.A. rawhide. They do not blend US hide with imported hide and they do not send hides to Mexico for processing and bring them back to the states. Wholesome Hide American made, premium rawhide is healthier for dogs because fresh, natural USA beef hides are used with none of the potentially harmful chemicals needed to treat poor quality hide. Dogs love them because they are made with fresh, 100 percent USA beef hide that still contains the tasty Collagen Flavor Layer, making them thicker so dogs can enjoy them longer. Many imported rawhide is made from poorer grade hide that has lost its flavor and durability through heavy processing. These tasty USA rawhide square knot bones measure about 7-8 inches long.
