Fight doggie breath the natural way and give him something to wag about with Zuke's Mini Z-Bones Clean Berry Crisp flavor. Z-Bones help freshen breath and clean teeth without having to use wheat gluten, cornstarch or synthetic chlorophyll. Zuke's potato-based chews maintain dental hygiene by scraping and polishing your dogs teeth. The firm texture helps clean teeth and gums, and fennel starts working in the mouth right away. On the inside, Z-Bones help improve digestion with alfalfa, parsley and rosemary, keeping doggie breath at bay for the long haul.
