Abstract

A wide range of aqueous based soaking operations can be employed to impregnate substantially throughout various rawhide pet chews; suitable substances for release into the oral cavity of pets during chewing include emulsions, surfactants, conditioners, flavorants and/or active ingredients. Prior to impregnation, the rawhide chews are physically disrupted/penetrated to augment substance impregnation substantially throughout the chews.
