Dogs can eat sweet potatoes safely when they are cooked and unseasoned. Sweet potatoes are nutritious for dogs, providing dietary fiber, vitamins (A, B6, C), minerals (iron, calcium, selenium), and antioxidants like beta-carotene, which support eye health, digestion, and immune function. However, sweet potatoes should be given in moderation and not make up more than 10% of a dog's daily caloric intake to avoid digestive issues or weight gain. Raw sweet potatoes and sweet potato skin are not ideal due to difficulty in digestion and potential choking hazards. It is always recommended to consult a veterinarian before introducing sweet potatoes or any new food to a dog's diet, especially for dogs with preexisting health conditions or dietary restrictions.
