Can Dogs Eat Potatoes? Raw vs Cooked
Start here
Yes if cooked and plain; never raw. Plain cooked potatoes (boiled or baked, no butter, salt, or seasoning) are safe in small amounts for most dogs. Raw potatoes and any green, sprouted parts contain solanine, which is toxic, so those should always be avoided.
Are potatoes safe for dogs?
Cooked, plain potatoes are generally safe for dogs in moderation. Potatoes are a starchy vegetable that provides carbohydrates, some vitamins (like C and B6), and minerals such as potassium. Cooking breaks down the starch and makes them easier to digest.
Because they're high in carbohydrates, potatoes are best as an occasional treat rather than a big part of the diet, especially for overweight or diabetic dogs. If your dog has diabetes, check with your vet first, as potatoes can spike blood sugar.
Why are raw potatoes a problem?
Raw potatoes, and the green skin, eyes, or sprouts of any potato, contain solanine, a natural compound that's toxic to dogs (and people). Cooking greatly reduces solanine in the flesh, which is why cooked potato is fine but raw is not.
Signs of solanine poisoning can include vomiting, diarrhea, lethargy, weakness, confusion, and, in serious cases, changes in heart rate. Never feed raw potato, and store potatoes somewhere your dog can't help themselves. Green or sprouting potatoes should be kept away entirely.
How should I serve potatoes?
Keep preparation plain and simple:
- Cook them by boiling or baking, with no oil.
- No butter, salt, gravy, cheese, garlic, or onion, which are either unhealthy or toxic.
- Serve a small amount, plain, cut into manageable pieces.
- Skip fries, chips, and mashed potatoes made with dairy and seasoning.
A spoonful of plain cooked potato mixed into food is plenty for most dogs. Introduce it slowly and watch for any digestive upset.
What about sweet potatoes and other forms?
Sweet potatoes are a popular, nutritious alternative: cooked, plain, and unseasoned, they're safe and rich in fiber and vitamin A. As with regular potatoes, avoid raw sweet potato and never add butter or seasoning.
Because potatoes are carb-heavy, they can quietly add calories. Tracking your dog's weight and treat portions in Tavi helps you notice if starchy extras are nudging the scale up over time. If your dog ate raw or green potato and seems unwell, call your vet or the ASPCA Animal Poison Control Center at (888) 426-4435.
Frequently asked questions
Can dogs eat raw potatoes?
No. Raw potatoes contain solanine, a compound toxic to dogs, and are also hard to digest. Green, sprouted, or unripe potatoes have especially high solanine levels. Only plain, thoroughly cooked potato flesh (boiled or baked, with no butter or seasoning) is safe, and even then only in small amounts.
Are mashed potatoes okay for dogs?
Plain mashed potatoes made with just cooked potato are fine in small amounts, but most mashed potatoes are made with butter, milk, salt, and sometimes garlic, which are unhealthy or toxic for dogs. If you want to share, set aside a little plain, unseasoned cooked potato before adding any ingredients.
Can dogs eat potato skins?
It's safest to avoid them. Skins can carry higher concentrations of solanine, especially if green, and they're harder to digest. Fried or seasoned potato skins add unhealthy fat and salt. Stick to a small amount of peeled, plain cooked potato flesh if you want to share this vegetable.
Are sweet potatoes better for dogs than regular potatoes?
Sweet potatoes are a nutritious choice, offering fiber, vitamin A, and antioxidants, and many dog foods and treats use them. Like regular potatoes, they must be cooked and served plain, never raw or seasoned. Both are carbohydrate-rich, so keep portions small, particularly for overweight or diabetic dogs.
