A formed dog chew is produced by molding, extrusion or other fabrication technique, and includes, as a forming material, a corn or wheat based polymer, nylon or other non-toxic polymer, whether digestible or undigestible, which has not been shown harmful if ingested by an animal, to which is added any of various additives which impart various benefits purportedly associated with such substances when the dog chew is gnawed by the pet by virtue of release thereof into the dog's mouth as the chew is gradually consumed over time.
