Instead of traditional extruding methods, all our formulas use a unique process called a Vacuum Infusion System or VIS. We only use free-run Canadian chicken and wild-caught, sustainable herring, sardines and anchovies that are ethoxiquin free in our products. We could talk about Virgin Coconut Oil all day long! It's one of our favorite superfoods in all our pet food and treat formulas. With the addition of whole raspberries, blueberries and cranberries, Laughing Dog added even more punch to our superfood. Ingredient quality matters to us at Laughing Dog.
