While just about any pet can be taught to sit, shake, and spin, very few have mastered the morning routine of gargling. Ark Naturals Plaque-Zapper Water Additive Dog & Cat Pouches keep teeth and gums healthy by neutralizing pH levels in your pet's saliva and help prevent harmful bacteria from growing. Pour one packet into your pet's drinking water once a day, 3 times a week. Let the tasteless, odorless, and colorless miracle go to work! Plaque-Zapper Small to Medium pouches are carefully crafted in the USA.
