- The starter bone (center of the pack) is made with soft, flexible material explicitly designed for teething puppies who have not formed any adult teeth.
- Graduate to the blue dental bone with nubs once your puppy has some adult teeth. This chew is made of soft, but durable, long-lasting non-toxic nylon
- The white extreme chew is harder for when your puppy’s chewing style develops and he has adult teeth
- Great for dental hygiene, tiny bristles raise on the bone during chewing, like a mini toothbrush to help keep teeth clean and prevent tartar build-up
