Quick Overview Made of very thick slabs of sweet potato, dehydrated. Designed for larger breeds, but smaller dogs will enjoy them as well and they will last them a good long time. Each slice is perforated in order to assist in the dehydration of such a large piece. The surface is hard so as to provide dental benefits, yet the chews have a texture similar to rawhide. Each chew has the nutritional value of half of a large sweet potato.
