Zuke’s Z-Bones grain-free dental chews are designed to clean teeth and freshen breath for dogs while also delivering antioxidants from sources such as spinach, rosemary, alfalfa concentrate and turmeric. Z-Bones have a raised Z Ridge surface that scrapes and polishes the surface of teeth, and the bone's texture encourages a longer chew time. Ingredients such as clove, vanilla, parsley and fennel aim to freshen breath. The chews are available in Clean Carrot Crunch, Clean Cherry Berry and Clean Apple Crisp.
