Rawhide chews are cut from animal hide and sold as rolls, chips, sticks and retrievers. The choices here are mostly about shape and length: a roll lasts longer than a chip, and a retriever is a long rolled chew. Check the length in inches against your dog's size and see whether the pack is sold by weight, by the piece or as a mixed value pack. Follow the maker's directions on each page. To see chews without hide, open rawhide free chews.
