Ollos helps prevent oxidation in your pet by regulating the pH that causes the brown or reddish discoloration of bodily fluids, which can eventually stain the fur around your pet's eyes or paws if they lick themselves. Ollos' natural ingredients are chosen for your pet's well-being. Simply add Ollos to your pet's food daily to maximize its impact on the digestive system. This process, from the inside out, helps neutralize the pH of the mucous membranes, reducing discoloration.
