Keeping your dog healthy involves more than providing food and fresh water. Just like humans, dogs need essential vitamins and minerals to support growth, maintain a strong immune system, promote healthy skin and coat, and keep their bones and muscles functioning properly. While many high-quality commercial dog foods are formulated to provide complete nutrition, some dogs may benefit from additional vitamins under the guidance of a veterinarian.
