  • Patent number: 6050224
    Abstract: A therapeutic chew device for aiding against periodontal disease in dogs which includes a length of rope formed of a plurality of polyester yarns with knots near the opposite ends of the rope and a chewable rawhide disk, including a compressed rawhide chew impregnated with activated charcoal, attached to the length of rope between the two knot. As the dog chews on the rope, the plurality of polyester yarns massage and stimulate the gums while individual loose yarn ends provide cleaning and flossing action for the teeth. In addition, as the dog chews on the charcoal impregnated rawhide disk, the activated charcoal is slowly released and absorbs odors and bacteria to clean and freshen the dog's breath.
