No canine adult diet on the market has proven itself like Wysong Adult™ (formerly Maintenance™). It is created by a veterinarian and owes its popularity solely to veterinary recommendation and word of mouth. Adult™ has been fed to tens of thousands of canines through multiple generations for over thirty years with remarkable results. This improved formulation is designed to take advantage of new processing methods to preserve natural value, and nutritional advances in epigenetics and nutrigenomics. Adult™ is higher in meats, organs, protein, and fat, and contains a comprehensive spectrum and higher levels of micronutrients/nutraceuticals including prebiotics, probiotics, enzymes, omega-3s, antioxidants and more. Small quantities of fruits and vegetables mimic what may be consumed in the viscera of prey, and contribute important vitamins, minerals, antioxidants and other nutrients.
