Now your pets can brush their own teeth with these convenient chews. The outside ridges are covered with natural breath-freshening ingredients such as chlorophyll, cinnamon, vanilla and clove, and the middle is filled with a brushless toothpaste. Abrasive action provides effective teeth scrubbing to control the plaque, tartar and bacteria that causes bad breath. For dogs 12 weeks and older (and cats too, if they like the taste!)
