Potatoes belong to the nightshade family, so can dogs eat potatoes safely? It depends on the potato’s condition and how it’s prepared. A plain, cooked spud is a harmless snack. A raw, green or sprouting one is not. Below: which forms are safe, how to cook them, how much to share, and what to do if your dog raids the potato bag.
Yes, if they’re cooked and plain. Peeled, boiled or baked white potato with nothing added is safe in small amounts. Avoid raw potatoes, any potato with green patches or sprouts, and the plant’s leaves and stems. Skip buttery mashed potatoes, fries and tater tots too.

Raw, Green or Cooked: Why the Form Matters
Potatoes naturally contain solanine, a bitter compound the plant makes to protect itself. According to Poison Control, the highest levels sit in the leaves, flowers, “eyes,” green skin and sprouts. Here’s the part many people miss: baking, boiling, frying or microwaving doesn’t destroy it. Peeling and cutting away green spots is what lowers it.
| Potato Form | Safe for Dogs? | Why |
|---|---|---|
| Plain boiled or baked, peeled | Yes, in moderation | Soft, easy to digest, low in solanine |
| Plain cooked with skin | Usually, if the skin isn’t green | Skin holds more solanine and is harder to digest |
| Raw potato | No | Hard to digest, choking risk, more solanine than peeled cooked flesh |
| Green, sprouted or “eyed” potato | No | Highest solanine levels, and cooking won’t fix it |
| Leaves, stems, flowers | No | Concentrated solanine |
| Mashed, fried, chips, tater tots | Not recommended | Butter, oil, salt, garlic or onion |
Nutrition Snapshot: Potato vs. Rice
Rice and potato are the two starches owners reach for most, so here’s how they compare per 100 grams of plain, cooked food, based on USDA data:
| Per 100 g, cooked | Boiled Potato (no skin) | White Rice |
|---|---|---|
| Calories | ~87 kcal | ~130 kcal |
| Carbohydrates | ~20 g | ~28 g |
| Fiber | ~1.8 g | ~0.4 g |
| Potassium | ~379 mg | ~35 mg |
| Vitamin C | ~13 mg | 0 mg |
Approximate USDA FoodData Central values. Dogs make their own vitamin C, so it’s a bonus rather than a need.
Potato wins on fiber and potassium, and it’s lighter in calories. Rice is blander and is still the more common choice in vet-recommended recovery diets. Neither is “better” for every dog. Both are just carbohydrates, so they work best as small extras rather than meal replacements.
How to Cook Potatoes for Dogs
- Pick firm potatoes with no green tint, soft spots or sprouts.
- Peel them, and cut out any eyes.
- Boil or bake plain until soft all the way through. No salt, butter, oil, cheese, sour cream, garlic or onion.
- Cool and cube or mash with a splash of the cooking water instead of milk.
How Much Potato Can a Dog Eat?
A 1-inch cube of boiled potato weighs about 17 grams and has roughly 15 calories. Keep it a side treat, not a meal:
| Dog Size | Weight | Plain Cooked Potato | Approx. Calories |
|---|---|---|---|
| Toy | Under 10 lb | 2–4 half-inch cubes | 4–8 kcal |
| Small | 10–25 lb | 1–2 one-inch cubes | 15–30 kcal |
| Medium | 25–50 lb | 2–3 one-inch cubes | 30–45 kcal |
| Large | 50–90 lb | 3–4 one-inch cubes | 45–60 kcal |
| Giant | 90+ lb | Up to 5 one-inch cubes | ~75 kcal |
A few times a week for healthy adults. Dogs with diabetes or weight issues should check with a vet first, since potatoes are starchy.
Can Dogs Eat Mashed Potatoes? Plus Fries and Tater Tots
The potato itself isn’t the issue here. It’s everything we add. In the AKC’s guide, a veterinarian explains that cooked potatoes are fine, but not with lots of butter, which can trigger pancreatitis.
- Mashed potatoes: often made with butter, cream, salt, and sometimes garlic or chives, which are toxic to dogs.
- Fries, tater tots and chips: deep-fried and heavily salted.
- Loaded baked potatoes: sour cream, cheese, bacon bits and green onions stack up fast.
A lick of plain mash that fell on the floor won’t usually hurt. A whole holiday bowl is a different matter.
How to make dog-safe mashed potatoes
If you want your dog to share in a holiday meal, set some potato aside before the butter and seasoning go in:
- Peel the potato and remove any green spots or sprouts.
- Boil until very soft, with no salt in the water.
- Mash with a splash of the cooking water instead of milk or butter.
- Cool and serve a spoonful on top of your dog’s regular food.
Keep it small: about 1 tablespoon for a 10 lb dog and up to ¼ cup for a large dog, counted as part of the day’s treats. For the rest of the holiday table, see what Thanksgiving food dogs can eat.
Are Potatoes Good for an Upset Stomach?
Some vets suggest plain boiled potato as a stand-in for rice in a short-term bland diet, since it’s soft and easy on the gut without fat. Treat it as a few-day fix, not a diet. If diarrhea lasts more than a day or two, contains blood, or comes with vomiting or lethargy, call your vet, even if your dog seems otherwise normal.
Potatoes also appear in many grain-free dog foods. The FDA’s review of a possible link between those diets and heart disease found no proven cause. Still, if potatoes or legumes top your dog food’s ingredient list, it’s worth raising with your vet.
Signs of solanine poisoning to watch for after eating raw, green or sprouted potatoes or potato plants:
- Vomiting, diarrhea or drooling
- Weakness, sleepiness or confusion
- Dilated pupils or a slow heart rate
Call your vet or an animal poison control center right away and tell them roughly how much your dog ate.

Frequently Asked Questions
How much raw potato is toxic to a dog?
There’s no reliable cutoff, because solanine levels vary a lot from potato to potato. A small bite of fresh, unpeeled raw potato is unlikely to cause more than an upset stomach. Green or sprouted potatoes, or a large amount, are more concerning. Call your vet with your dog’s weight and what they ate.
What happens if a dog eats a baked potato?
A plain baked potato is generally fine. If it was loaded with butter, sour cream, cheese or chives, watch for vomiting, diarrhea or signs of belly pain over the next day or two.
Can dogs eat potatoes every day?
It’s better not to. Potatoes are starchy and add calories without offering much that your dog’s regular food doesn’t already provide. A few small pieces a couple of times a week is a more sensible rhythm.
Can I give my dog stuffing or potato salad?
No. Stuffing usually contains onion, garlic, herbs and butter, and potato salad is full of mayonnaise and often onion. Both are better kept on your plate.
Can dogs eat potato skins?
Small amounts of cooked, non-green skin are okay. Peeling is still the safer default, especially for small dogs.
Is boiled potato good for dogs?
Plain boiled potato is one of the safest ways to share it. It offers some fiber and potassium, but your dog doesn’t need it if they’re eating a complete diet.

The Bottom Line
Can dogs eat potatoes? Yes, when they’re peeled, cooked and plain. Throw away green or sprouted spuds, keep the potato plant out of reach, and save the butter-and-salt sides for the humans. For a lighter, sweeter treat, a few slices of banana work well, and you can find more food guides in our Can Dogs Eat…? section.
