BetterBoneMedium Density is a perfect middle ground between our Hard and Soft Density. Made from two natural ingredients, our bones are healthier, safer, and delicious. The best part is, there is NO NYLON in any BetterBone. This is our Mini size which is recommended for tiny breeds (under 15 lbs). Our beef flavor uses dehydrated beef to make your dog salivate and enjoy their BetterBone even more! Flaking is to be expected and is splinter resistant splinter. Our material flakes to better protect teeth and could be a little messy but this is to protect teeth! Not a meal replacement. Monitor your dog while chewing, like you would any other toy. Enjoy! Special Features: BetterBone Medium is the perfect middle ground between our Hard and Soft Densities. Crafted from all-natural, food-grade ingredients, it is designed to promote health and dental hygiene with its super durable natural, food-grade, GMO-free ingredients. Our unique teeth-cleaning ends reach tricky, hard-to-clean areas.
