The thickness of the epidermis varies with different animals, for example, the thickness of the epidermis of cowhide is 0.5 to 1.5% of the total thickness; sheepskin and goatskin is 2 to 3%; and pigskin is 2 to 5%. Dermis is located under the epidermis, between the epidermis and subcutaneous tissue, is the main part of the rawhide. Its weight or thickness accounts for about 90% or more of rawhide.
