Your dog is hard-wired to chew, chew, chew. Encouraging this instinctual behavior by providing your canine companion with an appropriate chewing item can promote mental and emotional wellbeing along with dental benefits. The Hartz Chew 'n Clean Dental Duo is a long-lasting chew toy and treat all in one! It's constructed from durable materials that withstand mild to moderate chewing. Enriched with a delicious, edible bacon flavored center and our DentaShield technology, the Dental Duo reduces new tartar formation by bonding with components in your dog’s saliva. The chewing action helps reduce tartar build-up, freshen breath and promote healthy gums. Available in a variety of sizes and colors to suit every dog's needs. Remember to supervise your pup with any toy. Always provide plenty of water. Supervise your pet. Not a childs toy. Toy should be removed and replaced if excessive wear occurs.
