Dogs have the natural compulsion to chew in order to relieve stress or cure boredom. This is especially true for puppies. For any dog, the need to chew is an urge that must be satisfied. Instead of sacrificing your shoes to the puppy's chewing urge, give the dog something beneficial to chew with CET's brand of chews. These chewy strips work like rawhide pieces to help your dog exercise his natural need to chew. They also prevent excess stress on the teeth and gums. Unlike rawhide, the CET HEXtra Premium Chews contain chlorhexidine, an antiseptic that helps clean your dog's mouth every time the dog chomps down on the CET chews. These strips are also petite to fit a small dog's mouth. The CET HEXtra Premium Chews are made to please any dog, no matter his or her size.
