Ark Naturals Plaque Zapper is a water booster with enzymes to help reduce and prevent plaque and tartar buildup in your dog or cat’s mouth. Plaque Zapper contains natural enzymes that are activated by mouth saliva, and as your pet drinks the water, it kills harmful mouth bacteria. Plaque Zapper enzymes help prevent plaque from sticking to your pets' teeth, and help reduce the growth of oral bacteria that cause bad breath and tooth decay.
