Can Dogs Eat Potatoes? 2026 Vet Guide
Quick Answer: ⚠ SOMETIMES — Use Caution
Sometimes — cooked, plain white potatoes are safe, but raw potatoes are harmful.
Plain cooked potatoes are safe for dogs in small amounts, but they require more careful preparation than many other vegetables due to the solanine content of raw and green potatoes. The cooking and selection process matters significantly.
Nutritional Benefits
Cooked potatoes provide carbohydrates for energy, vitamin C, potassium, iron, and magnesium. They are easily digestible when plain and cooked, which is why potato is a common ingredient in commercial dog foods and sensitive-stomach diets.
Risks to Know
Raw potatoes contain solanine, a glycoalkaloid toxin (also found in raw green tomatoes). Solanine is concentrated in the skin and green parts of the potato. Green potatoes have particularly high solanine levels. Potato skins, when fed in large amounts, can also cause digestive issues. French fries, mashed potatoes with butter, and chips are all too high in fat and salt.
How to Serve Potatoes Safely to Dogs
Boil or bake plain potatoes (peeled for best safety). No salt, butter, sour cream, or seasonings. Allow to cool before serving. Serve as a small addition to regular food, not as a meal replacement.
How Much Potatoes Is Safe for Dogs?
One to two tablespoons for small dogs; up to a quarter cup for large dogs. Potatoes should be an occasional addition, not a daily staple.
Solanine in Potatoes
Solanine is a glycoalkaloid naturally produced by potato plants as a pest deterrent. It concentrates in the green skin, green flesh, sprouts (‘eyes’), and especially in green potatoes. Cooking reduces—but does not completely eliminate—solanine. The ASPCA classifies raw potatoes and potato plants as toxic to dogs. For this reason, only fully ripe, cooked, peeled potatoes should be offered to dogs.
Frequently Asked Questions
Q: Can dogs eat potato skin?
Cooked potato skin in small amounts is not acutely toxic, but it can cause GI upset. Raw or green potato skin contains solanine and should never be fed.
Q: Are sweet potatoes better than white potatoes for dogs?
Yes. Sweet potatoes have more nutritional value, lower glycemic impact, and are safer to serve since they do not contain solanine.
Q: Can dogs eat potato chips?
No. Chips are fried in unhealthy oils and contain large amounts of salt. Even one serving of chips can be too much sodium for a small dog.
Q: Are mashed potatoes safe for dogs?
Plain mashed potato with no butter, milk, salt, or spices is safe in small amounts. Restaurant or home-style mashed potatoes typically contain all of these additives and should not be shared.
