Take a look at the Nylabone 101 video above, and if you have an extra minute, watch Paige the wonderdog save Dexter's bacon with Nylabone! Very cute.
 
Nylabone® Puppy Teething Pacifier and Teething Keys are made of soft, flexible material designed especially for teething puppies. Helps clean teeth, controls tartar and plaque build-up at the same time! Fun shapes keep your puppy's interest. Not for puppies with adult teeth, as the material used for these teethers is softer. These teething rings might also be appropriate for smaller dogs who are gentle chewers.
 
The teething ring has small bumps to help relieve pain and clean teeth. On the teething keys, small bristle-like projections will be raised, which help clean teeth and massage gums. This is not a consumable product but small shavings (no larger than a grain of rice) should pass through without effect. Made in the U.S.
 
The teething pacifier comes in one size.
 
Three sizes of teething keys
X-Small  up to 15 lbs.
   Small  up to 25 lbs.
   Large  up to 35 lbs.
 
Always supervise your dog's use of toys.
