Can Dogs Eat Potatoes? Should They Be In A Dogs Diet?

Potatoes have a bad rep: They’ve been called names (couch potato!) and they’ve been demonized when it comes to putting them in our dogs’ food. But are the really that unhealthy? Or are we projecting our own issues with carbs onto our pups again? To answer this, we turned to Korinn Saker, DVM, Ph.D., an associate professor of clinical nutrition at North Carolina State University. “I suspect that it is in part consumer concerns regarding the starch associated with white potatoes,” Saker Says. We peel back the layers on this complicated nutritional topic by answering some of humans most common questions about potatoes:

Can Dogs Eat Potatoes?

Yes, dogs can eat potatoes—but only when they’re cooked and served plain. Raw potatoes, especially green ones, contain solanine, a natural compound that can be toxic to dogs in high amounts. Cooking potatoes helps reduce the solanine levels, making them safer to eat. Boiled, baked, or steamed potatoes without added butter, salt, or seasonings are the safest options.

Are Potatoes Good For Dogs?

Potatoes can be a source of energy thanks to their carbohydrate content, but they don’t offer as many nutrients as other vegetables. They contain some vitamin C, potassium, and fiber, but should only be a small part of your dog’s overall diet. For dogs with weight issues or diabetes, potatoes may not be the best choice because they can spike blood sugar.

In moderation, plain cooked potatoes can be a safe, occasional addition to your dog’s meals. Just skip the fries, chips, and mashed potatoes with extras. And as always, check with your vet before introducing new foods—especially if your dog has specific health conditions or dietary needs.

Are potatoes dangerous for dogs?

Raw potatoes contain solanine, which can slow down your pup’s heart, blur his vision and obstruct his digestion—it’s especially prevalent in the sprouts and on the green parts. But as long as they’re cooked, and all stems and shoots are removed before cooking, potatoes themselves pose no risk to most dogs, Saker says. Otherwise, potatoes should be avoided if your dog has hyperkalemia (high blood potassium concentration) or end stage renal disease. And since they can cause blood sugar spikes, they aren’t recommended for dogs with diabetes.

What about potato allergies?

Potatoes are one of the most common allergies reported for dogs—signs include chronic gas, frequent ear infections, bald patches and hives. That being said, many humans think their dogs are allergic to potatoes when they actually aren’t: “There is a very, very low chance of an individual having an allergy to potato starch,” says Saker. If you suspect your pup is allergic, you can do an elimination diet or run a blood test, but they are generally unreliable. In fact, if there is a concern of potential allergies to a grain carbohydrate, potato is a common substitute carb.

Are white potatoes healthy for dogs?

“If prepared correctly, potatoes are a good, acceptable carbohydrate source in a dog’s diet,” she says. They’re very rich in potassium, Vitamins C, B6 and B3, magnesium, iron, copper and fiber, along with antioxidants. In fact, a study by the USDA’s Agricultural Research Service found more than 60 different vitamins and phytochemical in potatoes that support heart health, immunity and protect against cancer. So they’re pretty healthy for pups!

Are sweet potatoes better for dogs?

Sweet potatoes have more starch and provide more fiber, Saker says. Both are high in potassium, but sweet potatoes are a very rich source of beta-carotene (dogs convert this to Vitamin A, which is beneficial for healthy vision and supports a healthy immune system). Sweet potatoes are also rich in anthocyanins, which have health benefits such as antioxidants and anti-inflammatory nutrients. So sweet may be preferable, but that doesn’t mean white ones are necessarily bad.

So what’s the verdict?

If your dog isn’t truly allergic (check with a vet for that one), potatoes are perfectly fine to include in his diet – as long as they’re in moderation. And stay away from raw potatoes and potato chips, no matter how badly your pup wants his own bag.
