Nylabone Dental Dog ChewVeterinarian recommended Dental Chews are designed to massage gums and scrape and clean teeth of food particles and tartar. The result is a healthier mouth and fresher breath. Their round, pliable dental nubs gently massage the gums and stimulate an increase in healthy fluids and saliva flow in the mouth while the friction against the teeth helps remove food debris and bacteria that leads to tartar formation. Recommended for average chewers.
