Make your puppy happy to chew & play, with his bone toy he will never feel lonely. SAFE TO CHEW: Our bones are made of food grade nylon, not rubber. Keep his teeth healthy, let him chew and enjoy the bacon taste of his new toy. Note: We love our dogs just as much as you do. Our bones are durable, but not indestructible, as aggressive chewers replace it every 6 months. Make sure he won’t swallow it, use our size chart to select his right size to take care of your pet.
