VéRUS Cold Water Fish Holistic Formula is a combination of great tasting, highly digestible, nutrient dense, fresh cold water ocean fish, vegetables, and legumes providing complete and balanced nutrition for all life stages of your dog. We start with fresh salmon and Omega 3 rich menhaden and herring meat protein to give our food a taste your dog can't resist. Then we combine lentils, chickpeas, split green peas, and yams as a healthy rich organic source of vitamins, minerals, and complex carbohydrates. Added to this unique formula is Omega 3 rich menhaden fish oil to provide healthy benefits for the immune system and skin and coat. We top this formula off with our exclusive (non-Chinese) sourced vitamins and chelated minerals for nutritional insurance.
