There are dogs that, for various reasons such as protein intolerances due to allergies, cannot be fed with a varied diet or are inadequately fed. Over time, these dogs may experience nutrient deficiencies. There are also cases where a dog has special nutrient requirements. For all these dogs, we have developed the Vitamin-Mineral Booster. This turns each SANADOG menu into a complete meal when fed individually. The booster contains all the essential vitamins and minerals.
