The Hoof itself is a great puppy teether. Hooves are cartilage, not bone, so the splintering factor is greatly reduced. Because it’s cartilage, it’s not as hard as bone, and gums up a little as it’s chewed, but it’s still hard enough to scrub those puppy teeth and gums just like a toothbrush. The Hoof is easy to fill with other ingredients to entice a puppy – a tiny swipe of peanut butter inside is enough to get a dog chewing. Or you could just buy the Stuffed Hooves and keep your dog occupied longer.
