Can dogs eat potatoes?

Caution — cooked only, no raw or green

Plain cooked potato is fine in small amounts. Raw potatoes, green potatoes, and potato sprouts contain solanine and are toxic.

The full picture

Like tomatoes, potatoes are nightshades and contain solanine — concentrated in the skin, sprouts, and any green parts. Cooking destroys much of the toxin, which is why plain boiled, baked, or steamed potato flesh is generally safe. Raw potato, green potato, or sprouted potato should never be fed. Chips, crisps, and roast potatoes cooked with salt, oil, and seasonings are separate issues. A few pieces of plain cooked potato mixed into a meal is fine; a high-potato diet isn't ideal.
