Can Dogs Eat Sweet Potatoes? Benefits, Risks, and Safe Serving Tips

Yes, dogs can eat sweet potatoes as long as they are fully cooked, plain, and served in moderation. Cooked sweet potato is a good source of fiber, beta-carotene, and vitamins, which is why it shows up in so many commercial dog foods and treats. Raw sweet potato, the skin, and anything made with butter, sugar, marshmallows, or spices are a different story.

Sweet potatoes are everywhere in the fall, from weeknight sides to the Thanksgiving casserole. Here is what makes plain sweet potato a healthy occasional treat, which versions to keep away from your dog, and how to serve it safely.

Are Sweet Potatoes Good for Dogs?

For most healthy dogs, a little plain sweet potato is a nutritious extra. According to PetMD, sweet potatoes provide fiber, antioxidants, and vitamins and minerals, and they are a common carbohydrate in commercial dog foods for that reason. The American Kennel Club also notes that sweet potatoes are low in fat and contain vitamins A, B6, and C along with calcium, potassium, and iron.

Here is what that means for your dog:

• Fiber for digestion. The fiber in cooked sweet potato supports normal digestion and can help some dogs feel full.
• Beta-carotene. Like carrots and pumpkin, sweet potatoes are orange because of beta-carotene, which a dog’s body converts into vitamin A for eye, skin, and immune health.
• Vitamins and minerals. Vitamin C, vitamin B6, potassium, and manganese all come along in a small serving.
• A whole-food treat. Plain sweet potato has no added sugar or preservatives, which makes it a simple alternative to many store-bought snacks.

Sweet potato is a treat, not a meal. Your dog still needs a complete and balanced dog food, with animal protein as the foundation of its diet.

Sweet Potatoes vs. Regular Potatoes

Sweet potatoes and white potatoes are not closely related, and they come with different concerns. Raw white potatoes and their green parts contain solanine, which is why the rules for them are stricter. If you are curious about the white kind, our guide on whether dogs can eat potatoes covers it in detail. With sweet potatoes, the main issues are raw texture, the skin, portion size, and what gets added in the kitchen.

When Sweet Potatoes Are Bad for Dogs

Sweet potatoes are not toxic, but the way they are prepared and how much your dog eats can turn a healthy snack into a problem.

• Raw sweet potato. The AKC warns never to feed raw sweet potato because it is difficult to chew, can upset the stomach, and may cause an intestinal blockage.
• The skin. Peel it first. The skin is tougher for dogs to digest.
• Big chunks. Dogs that gulp their food can choke on large pieces. Mashed or small soft cubes are safer. If your dog inhales everything, our article on why some dogs eat so fast explains how to slow things down.
• Too much at once. Extra fiber can cause gas, loose stool, or vomiting. Over time, a lot of any treat adds calories, and the AKC notes that very large amounts of vitamin A can cause problems as well.
• Dogs with diabetes or weight issues. Sweet potatoes are starchy. The AKC recommends extra caution for diabetic, overweight, or less active dogs, so ask your vet before adding them. Our dog weight chart can help you see where your dog stands.

Thanksgiving Sweet Potato Dishes to Keep Away From Dogs

The plain sweet potato is fine. The holiday versions usually are not. Watch out for these on the counter and the table:

• Sweet potato casserole topped with marshmallows, brown sugar, butter, or pecans. It is high in sugar and fat, and rich, fatty foods are a common trigger for stomach upset and pancreatitis.
• Sweet potato pie, which adds sugar, butter, and spices like nutmeg.
• Sweet potato fries and chips, which are fried and salted.
• Candied yams, cooked in syrup or sugar.
• Anything sugar-free. Some reduced-sugar recipes and toppings use xylitol, which is toxic to dogs.

The ASPCA keeps a list of people foods to avoid feeding pets, including xylitol and nuts. If your dog got into a dish with unknown ingredients, call your veterinarian or the ASPCA Animal Poison Control Center at (888) 426-4435 (a consultation fee may apply).

What About Sweet Potato in Dog Food?

You may have heard about the FDA looking into heart disease and certain dog foods. In 2018 the FDA began investigating reports of canine dilated cardiomyopathy (DCM) in dogs eating certain diets, many labeled grain-free, that listed peas, lentils, other legumes, or potatoes (including sweet potatoes) as main ingredients. Most of the reported foods contained peas or lentils, and a far smaller share contained potatoes. The FDA has said that adverse event reports alone do not establish a cause.

That investigation is about diets built around these ingredients, not an occasional bite of cooked sweet potato. If your dog eats a grain-free food heavy in legumes or potatoes, talk with your vet about whether it is the right fit.

How to Serve Sweet Potatoes to Your Dog

1. Wash and peel the sweet potato.
2. Cook it plain by baking, boiling, or steaming until it is soft all the way through.
3. Skip every add-on. No butter, oil, salt, sugar, cinnamon, nutmeg, or marshmallows.
4. Cool it and mash it or cut it into small, soft pieces.
5. Start small the first time and watch for gas, loose stool, or itching over the next day.

PetMD notes that treats, including sweet potato, should make up no more than 10% of your dog’s daily calories. The right amount depends on your dog’s size, activity level, and health, so check with your vet if you are unsure, especially for small dogs, puppies, or dogs on a special diet. If you are working on your dog’s weight, our tips to help your dog lose weight show how treats fit into the daily total.

Frequently Asked Questions

Can dogs eat raw sweet potatoes?

No. Raw sweet potato is hard for dogs to chew and digest, can upset the stomach, and may cause an intestinal blockage. Always cook it until soft.

Can dogs eat sweet potato skin?

It is best to remove it. The skin is tougher to digest, and a large piece could be a choking or blockage risk for some dogs.

Can dogs eat sweet potato casserole or pie?

No. These dishes usually contain sugar, butter, marshmallows, nuts, or spices, which can upset your dog’s stomach. If a recipe was sugar-free, it may contain xylitol, so check the ingredients and call your vet or a pet poison hotline.

Can puppies eat sweet potatoes?

Many puppies can have a small taste of plain cooked sweet potato, but their stomachs are sensitive and they need their complete puppy food first. Ask your vet before adding new foods.

Are sweet potatoes good for dogs with upset stomachs?

Plain cooked sweet potato is gentle and contains fiber, but vomiting or diarrhea can have many causes. Call your vet rather than treating a sick dog at home with food.

The Bottom Line

Dogs can eat sweet potatoes when they are peeled, fully cooked, plain, and kept to a small treat-sized portion. Skip raw sweet potato and the sugary, buttery holiday dishes, be extra careful with diabetic or overweight dogs, and talk with your vet if you have questions about your dog’s diet.
