Can Dogs Eat Potatoes? What Pet Parents Should Know

Potatoes are a staple in many of our own diets, whether baked, mashed, fried, or roasted. But when your dog gives you that hopeful look from under the dinner table, you might wonder: Can dogs eat potatoes safely?

Let’s dig into the question of whether dogs can have potatoes: what's safe, what’s not, and how to make sure your pup stays happy and healthy.

The Short Answer: It Depends on How It’s Prepared

Yes, dogs can eat cooked potatoes in moderation, but raw potatoes should be avoided. Raw potatoes, especially those with green spots, contain solanine, a naturally occurring compound that can be toxic to dogs if eaten in large amounts¹. Be sure to remove any green spots prior to cooking, as well.

Cooking breaks down solanine, making potatoes much safer to eat and can be best enjoyed as an occasional treat. For dogs already eating a complete and balanced diet, extra potatoes aren’t nutritionally necessary and can lead to unwanted weight gain. Remember that any additions to your dog’s diet should never make up more than 10% of their daily caloric intake.

Are Potatoes Good for Dogs?

When properly cooked and balanced within a complete diet, potatoes offer excellent nutritional benefits for dogs; they’re a rich source of essential vitamins and minerals, particularly vitamin C, potassium, B6, iron, magnesium, and fibre², nutrients dogs need for energy and digestion.

They’re also starchy and offer complex carbohydrates, which makes them a great source of energy, especially when used in commercial pet foods. Cooked potatoes are also rich in prebiotic fibre, which can support a healthy gut microbiome and good quality stools.

Can Dogs Eat Sweet Potatoes? Are Sweet Potatoes Good for Dogs?

Sweet potatoes and white potatoes complement one another, each offering a unique set of vitamins and minerals for your dog. Sweet potatoes are rich in dietary fibre, beta-carotene (a source of vitamin A), and antioxidants³ that support your dog’s immune system and gut health.

Boiled or baked sweet potatoes (without butter, sugar, or salt) make a gentle, nutritious addition to a dog’s diet. Just remember, too much fibre can upset their stomach, so start small.

Can Dogs Eat Mashed Potatoes?

Plain, cooked mashed potatoes are safe in small servings, but skip the extras.

Add-ins like butter, milk, salt, or garlic can quickly turn a simple dish into something harmful. Dogs don’t need the fat or seasoning, and dairy can cause digestive issues for some pups.

If you’re sharing mashed potatoes, make a small unseasoned portion before adding your own toppings.

Can Dogs Eat Potato Skins?

Potato skins aren’t toxic when cooked, but they can be hard to digest and may contain leftover solanine, especially if they come from green or sprouted potatoes. It’s best to peel potatoes first or at least remove any green areas before cooking.

Can Dogs Eat Raw Potatoes?

No. Raw potatoes can contain solanine, which can be toxic when consumed in large amounts and lead to digestive upset, lethargy, and confusion⁴. Always cook potatoes thoroughly and serve them plain.

Can Dogs Eat Potato Chips?

Sadly, no. Potato chips are loaded with salt, oil, and artificial flavouring. While sneaking a chip or two won’t cause serious harm, these are things your dog simply doesn’t need. Regularly feeding chips could lead to obesity over time.

Can Dogs Eat Boiled Potatoes?

Yes. Boiled potatoes without salt or butter are one of the safest ways to serve them, so long as they’ve cooled off! Cut them into bite-sized chunks, let them cool, and offer them occasionally as a treat or mixed into their food. Boiling preserves nutrients better than frying and keeps fat content low.

Are Potatoes in Dog Food Bad?

Potatoes and sweet potatoes are commonly used in commercial dog foods as a source of energy and dietary fibre. They’re not bad, what matters is the balance and overall nutritional profile of the food. If you’re unsure, talk to your veterinarian about your dog’s individual health needs.
