Can Dogs Eat Potatoes?
⚠️ In moderation — with a couple of catches
Raw potatoes and green skin/sprouts contain solanine, a nightshade-family toxin; french fries, hashbrowns, and buttered or salted preparations can trigger pancreatitis or GI upset. Plain cooked potato in small amounts is the only OK form.
Plain cooked potato in small amounts is fine. Skip raw potatoes, green skin, sprouts (solanine), and french fries / buttered or salted versions.
How much potatoes can my dog eat?
A 30-lb adult dog needs about 794 kcal/day, so treats should stay under 79 kcal. That's up to about 6 tablespoons of cooked plain potato a day as a treat.
A treat limit (10% of daily calories), not a target — assumes an adult dog. Puppies and special diets: use the full calculator.
AKC's vet expert frames cooked potato as an occasional treat, not a main meal — "if you decide to feed them potatoes, do so as a treat." The calculator above shows your dog's daily ceiling under the 10% treat rule; for most dogs a tablespoon or two of plain mashed potato is plenty for an occasional share.
Are potatoes good for dogs?
Cooked plain potato (flesh, no skin, no salt) is about 86 kcal per 100 g — mostly starch, with small amounts of vitamin C, vitamin B6, potassium, and fiber. It's a starchy carb, not a nutrition powerhouse — your dog's main nutrition should still come from a complete-and-balanced diet.
How to serve potatoes
- Cook plain and serve in small amounts — boiled, baked, or plain mashed (no butter, no salt, no garlic, no seasoning). Cool before serving.
- Skin on or off is fine, as long as the skin isn't green. Plain potato skin is digestible for most dogs; green skin contains solanine and should be cut away.
- Start with one tablespoon the first time and watch for any tummy upset before offering more.
What to avoid
- Never raw, and never any green parts (green skin, green flesh, sprouts). Raw and green potatoes contain solanine — a nightshade toxin that can cause vomiting, diarrhea, lethargy, and in large amounts neurological problems.
- Skip french fries, hashbrowns, potato chips, and other fried or heavily seasoned potato dishes — the oil, salt, and seasonings (especially onion or garlic) are the real problem.
- Skip buttered, salted, or spiced potatoes (loaded baked potatoes, instant mashed with milk and butter, garlic-roasted, etc.) — the butter alone can trigger pancreatitis, and milk/cream can upset a lactose-sensitive stomach.
- If your dog ate a green potato (or got into a bag of sprouting potatoes), watch for vomiting, diarrhea, lethargy, or muscle weakness, and call your vet right away — especially for smaller dogs or larger amounts.

Common questions
- Can dogs eat raw potatoes?
- No. PetMD's vet-reviewed guidance is clear: raw potatoes are hard to digest and should be avoided, and any green parts contain solanine — a nightshade toxin that can cause vomiting, diarrhea, lethargy, and in large amounts neurological problems. Always cook plain (boil, bake, or plain-mash) and skip anything green or sprouting.
- Can dogs eat mashed potatoes?
- Plain mashed potato — boiled and mashed with nothing added — is fine in small amounts. AKC's vet expert says plain mashed or soft cooked potatoes are fine in small amounts without the butter and spices. The catch is the typical Thanksgiving version: butter, milk, salt, garlic, sour cream. Those are the actual risks, not the potato itself.
- Can dogs eat french fries?
- No. AKC explicitly groups french fries and hashbrowns with the potato-based dishes you should avoid. The oil is the main problem (high fat can trigger pancreatitis), and fries are also heavy on salt and often seasoned. One stolen fry won't poison your dog, but don't make it a habit.
- Can dogs eat potato skins?
- Plain skin is fine for most dogs — AKC's vet expert says potato skins are okay too, but not if they are green. Green skin contains solanine and should be peeled off. PetMD adds that excessive amounts of potato skin are hard to digest, so don't feed a giant pile of skins on their own.
- Are potatoes good for dogs?
- Plain cooked potato won't hurt a healthy dog in moderation, and AKC says boiled or baked potatoes can offer a variety of health benefits and won't cause obesity or diabetes in moderation. But potato is mostly starch — it's not a nutrition powerhouse. Your dog's main nutrition should come from a complete-and-balanced diet; potato is an occasional treat, not a daily supplement.
- What if my dog ate a green potato or a sprout?
- Green potatoes and sprouts contain higher solanine, which can be toxic. A small lick or one bite probably won't cause a serious reaction in a medium or large dog, but watch closely for vomiting, diarrhea, lethargy, or muscle weakness over the next 12–24 hours. Call your vet right away if any of those show up, especially for small dogs or if your dog ate more than a bite — your vet may want to see them.
- Can puppies eat potato?
- A small amount of plain cooked potato as an occasional treat is generally fine for a healthy puppy, but puppies have very specific nutrition needs from puppy food and are more sensitive to GI upset. Check with your vet before adding any new food, and skip potato entirely if your puppy has a sensitive stomach.
