A pet deterrent device is herein disclosed wherein common household pets may be trained away from the negative habit of chewing on various household items. The pet deterrent device generally comprises an absorbent substrate having a non-toxic, foul tasting substance impregnated therein which is adapted to be easily applied to any household item including electrical power cords, family heirlooms, furniture, and the like. Suitable absorbent substrates include various fabric materials and thermoplastic compositions such as polyurethane. Upon biting a typical household item/pet deterrent device assembly, the pet receives a foul taste thereby providing immediate negative reinforcement and thus training the pet away from the negative chewing behavior.
