This is a horse rawhide.
The fibers on horse rawhide are tighter and smoother than on cow rawhide even though horse rawhide tends to be lighter than cow rawhide. The horse rawhide is also stronger than cow rawhide. The hides are 2 to 4 oz. weight and may have butcher cuts on one side. Rawhide is also referred to as parchment or vellum.
Horses are not an endangered species and are not subject to U.S. Fish and Wildlife import/export controls or to CITES.
The horses are not killed just for their hides. The rawhide is a by-product of the food industry.
