Abstract
A rawhide-derived dog chew wherein rawhide is comminuted and then melted as it is injection molded. The melting of the rawhide sterilizes it to prevent the foul odor normally associated with rawhide products, while the injection molding of the molten material allows much larger forms to be molded than is possible with the use of compression molding while yielding a consistency and chewability preferred by most dogs.
