NutraVet offers liquid supplements for your Dog or Cat that are effective, efficient, and affordable, including our NutraVet Pro20 Probiotic drops. Our Probiotic drops were specifically formulated in liquid form to allow your dog or cat easier and more efficient access to superior overall digestive health. Think of the good ingredients found in Pro20 as the internal janitors of the digestive system. NutraVet's probiotic drops protect your pet from the aging process by preventing the propagation of unhealthy items in your pet's stomach, destroying and inhibiting the growth of things that could harm your pet. With our unique liquid technology, our 20 strains of living, positive, organisms (probiotics) not only reach your dog or cat's intestinal tract but are also absorbed and don't pass through their system. Nothing can cause more havoc than stomach issues like diarrhea, food sensitivities, or GI distress. Keep your pet healthy, happy, and regular with a daily dose of NutraVet Pro20. IMPORTANT: This herb-based formula naturally ranges in color (even cloudiness), odor, and taste from batch to batch. NutraVet chooses not to hide these natural variations with synthetic ingredients to keep it as pure and naturally effective as possible. The appearance or smell of the ingredients (final product) has no impact on the effectiveness of the formula.
