BetterBone Hard Density is perfect for strong and aggressive chewing dogs with healthy teeth. 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 small size which is recommended for smaller breeds (15-45lbs). 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 HARD is the ultimate natural & durable chew toy for strong, tough, & aggressive chewers! 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.
