Chew Guards - A thick, heat treated plastic tubing which attaches to the sides of the HiK9 bed to help stop chewers biting the cover. Please note Chew Guards are made to order and may take a few weeks to be delivered. Fixes snuggly onto all four sides of the HiK9 bed. Won't splinter or fracture when bitten. Can be removed from the bed if needed. Our Chew Guards have been successful in deterring damage; tested in boarding kennels, police dog units and with service dogs. Saves money spent on replacement covers.
