The Playology Silver Dental Chew Ball is perfectly crafted to entertain your senior dog. It is made with softer materials that are gentle on aging teeth and gums, yet are durable and hold up to chewing. All the while, the deep grooves will clean your dog's teeth as they chew. This engaging chew toy is made with Playology's Encapsiscent Technology, which gives the toy a scent deep in the fibers of the toy that release as they chew. The scent is subtle though, so even though your pup loves it, you'll hardly notice it. Keep your old pal engaged, happy, and playing all while keeping their teeth and gums healthy.
