Magic Zeo Pro helps to loosen and easily remove stubborn tartar from your dog's teeth. It reduces bad breath and tartar buildup. Ideal for your dog's dental care. Magic Zeo uses the dual ion exchange action of super-electrolyzed water Magic Mist and natural zeolite to cover tartar and plaque with negative ions, promoting electrostatic repulsion with the tooth surface, thereby lifting and removing tartar and plaque from the tooth surface. Therefore, it doesn't damage the tooth surface. Shipped via Yamato Transport's Nekopos (mail delivery service).
