Abstract
A soft rawhide product is made by soaking raw animal hides in a humectant or combining chopped rawhide particles with the humectant and a soft edible binder. The humectant is taken up by the rawhide and provides a soft rawhide product even after the product is permitted to dry or is exposed to the air for long periods of time. The presence of the humectant and binder not only contribute to the softness of the rawhide product, but permits an increase in the moisture content and/or flexibility of the rawhide while still maintaining an acceptably low water activity. An additional benefit is an increased ability to import colors, flavors, scents, nutritional material or drugs into the edible chew toy product.
