Playology's Dual Layer Ring is a protein-scented chewable toy for dogs. It is ideal for heavy and the heaviest chewing dogs and its naturally-resilient non-toxic BPA-, phthalate- and lead-free extra-durable rubber is sheathed in slobber wicking performance material, which rinses clean in warm water. Featuring 100% all-natural made-in-the-USA protein scent embedded throughout its material, Dual Layer Ring helps create vigorous exercise-based play by triggering dogs' instinctive desire for food via their powerful olfactory organs and nerves. Pet owners, professional dog handlers, veterinarians and service dog trainers utilize this interactive dog toy to help canines stay alert, in shape, and always ready for lively physical exertion.

About: Dog lovers Adam and Lendy Beatty founded Playology to make dogs as fit and happy as possible. Studying the science behind what truly motivates canines, our dedicated team designed a colorful array of chew toys to stimulate dogs' dynamic sense of smell, which is roughly 10,000 times more powerful than ours. Trademarked "Encapsiscent Technology," Playology scientists encapsulate millions of microscopic protein derivatives throughout the whole toy, which excite dogs into chewing, gnawing, and fetching their way toward a stronger physique without unhealthy snacks. Inspiring highly-enthusiastic states of vigorous hunger-based cardiovascular exercise, all of our non-toxic dog toys can help pets stay healthy throughout their entire lives.
