Unless you have spoken with your vet about your dog’s vitamin needs, according to the American College of Veterinary Nutrition, your dog doesn’t need daily vitamins outside of what they get in their dog food. “If your pet is eating a complete and balanced commercially available pet food, supplements are not recommended unless specifically prescribed by your veterinarian.”
The vitamins dogs receive from their food daily include vitamins A, D, E, K, and B-complex vitamins. Your furry friend will also get calcium and phosphorus. Again, your dog’s food gives him exactly what he needs on a daily basis.
