Overview
Four Leaf Rover Protect is a veterinarian formulated probiotic powder for dogs, built around multiple bacterial strains plus prebiotics and antioxidants. This large dog size is meant to cover about 30 days of use.
Beyond the core probiotic strains, the formula adds organic blueberries, chlorella, humic and fulvic acid, and dandelion and burdock root, positioning it as a gut support blend rather than a single strain probiotic. It is aimed at stomach related use rather than general supplementation.
