The full picture
Cooked sweet potato is a dog superfood — rich in fiber, vitamin A, vitamin B6, vitamin C, and potassium. It's often used as an ingredient in high-quality dog food and is excellent for firming up loose stools in small quantities. The critical rule is that it must be cooked — raw sweet potato is difficult for dogs to digest and can cause intestinal blockages. Plain boiled, baked, or steamed sweet potato is ideal. Avoid adding butter, salt, or any seasonings, especially garlic or onion powder.

Why cooked, not raw?
Raw sweet potato is hard for dogs to digest and can cause an upset stomach or, in larger pieces, an obstruction risk — cooking (boiled, baked, or steamed, with no added butter, sugar, or seasoning) breaks down the starches and makes it far easier to digest. Never feed sweet potato pie filling or candied sweet potato, which typically contain added sugar and sometimes xylitol or spices unsuitable for dogs.
Does size or breed matter?
No toxicity concern at any size when properly cooked and plain. Sweet potato is calorie-dense, so portion should scale down for small and toy breeds and for any dog managing their weight.
