It’s Trivia Tuesday! ‘VO2 max’ measures a mammal’s maximum rate of oxygen consumption, reflecting aerobic fitness. Even couch potato dogs have a higher VO2 max than the most fit and conditioned human athlete. Learn more below! Even average family dogs that sleep most of the day have more endurance than the most conditioned human athlete, when comparing their VO2 max. This means that dogs consume more oxygen when exercising at maximum capacity, giving them increased aerobic energy and endurance. Unfortunately, all this oxygen “burn” means that dogs naturally produce free radicals - unstable particles that can injure cells. Antioxidants in food help counter free radicals. Active dogs that get less than adequate antioxidants may not perform at their best, particularly with consecutive days of exercise. They also may suffer muscle stiffness and disruption of cellular balance. Dogs need a rich antioxidant blend including selenium, and vitamins A and E, key nutrients that enrich Purina Pro Plan dry dog foods to help support your dog’s immune system and protect cells.
