Wysong Maintenance has been fed to tens of thousands of animals through multiple generations with great benefit. Maintenance is an all natural dog food formulated for adult dogs, but can be healthily fed to dogs of all life stages and types as part of a diet rotation. Unlike conventional dog foods which are often laden with food fractions and artificial non-nutritional additives, Maintenance is comprised of natural form and whole ingredients. Additionally, as with all other Wysong dry diets, Maintenance is coated with our proprietary probiotic and enzyme solution post-heat processing. This process restores many of the vital food components lost during the cooking/heat processing.
