  • Pet foods with water-soluble zinc compound coating for controlling malodorous breath
    Patent number: 5405836
    Abstract: Breath freshening, dry pet foods, e.g., pet biscuits are prepared by topically applying a breath freshening amount of a water-soluble zinc salt to a farinaceous-based baked or cooked pet food. The amount of the water-soluble zinc salt is sufficient so that said topically-applied water-soluble zinc salt contains from about 2 mg to about 6 mg of zinc ion per 10 gm of the breath freshening pet food. Consumption of the dry pet food controls the malodorous breath of the animal. Rawhide chew coated in the same manner also provides breath freshening when chewed.
