Can Dogs Eat Sweet Potatoes? A Complete Guide

Yes, in general, dogs can eat sweet potatoes. But remember to always consult your veterinarian before introducing any new foods into your pet’s diet, especially if they have any underlying health concerns such as food allergies, diabetes, etc.

Sweet potatoes are one of the best vegetables for us humans to eat. They provide an abundance of vitamins C and B6, which are great for your brain and nervous system health. And those are just a few of the wellness benefits they offer. But the question we’re here for is, can dogs have sweet potatoes? That answer is yes.

Even though humans and dogs have different nutritional needs, sweet potatoes provide many of the same health benefits to both us and them. Many Association of American Feed Control Officials (AAFCO)-approved dog foods have sweet potatoes among their ingredients, as they contain a healthy dose of dietary fiber, which helps the canine digestive system function effectively.

How to Feed Sweet Potatoes to Your Dog

Before adding sweet potatoes to your dog’s bowl, keep in mind that all treats offered throughout the day (including sweet potatoes) should amount to no more than 10 percent of your pet’s daily caloric intake.

Can dogs eat raw sweet potatoes? No. Prior to feeding your pet this tasty root vegetable, remove the skin and cook the rest thoroughly.

Can dogs eat sweet potato skins? No, skins should be avoided, as they can cause digestive issues. The skin also contains oxalates, which when fed in large quantities or too frequently may cause tremors, increased thirst and, ultimately, kidney damage. Raw sweet potatoes are not only hard to chew, but they also contain solanine, a toxin that can cause vomiting, diarrhea, lethargy or weakness in small amounts and more serious side effects in larger quantities. Once they’ve been skinned and cooked, sweet potatoes can be cut into bite-size pieces or mashed up for an extra treat or a topper for their dog food.

Frequently Asked Questions

Can dogs eat sweet potatoes every day? Sweet potatoes are nutritious, but they should be an occasional treat rather than a daily staple. All treats — sweet potatoes included — should make up no more than 10% of your dog's total daily caloric intake. Too much fiber from frequent feeding can lead to loose stools or diarrhea. Ask your veterinarian what portion size and frequency makes sense for your dog's size, age and activity level. https://sites.tufts.edu/petfoodology/

Can dogs eat raw sweet potatoes? No. Raw sweet potatoes contain solanine, a naturally occurring compound that can cause vomiting, diarrhea, lethargy and weakness — with more serious effects at higher quantities. Raw sweet potato is also very hard for dogs to chew and poses a choking risk. Always cook sweet potatoes thoroughly and remove the skin before offering them to your dog. https://www.aspca.org/pet-care/animal-poison-control

Can dogs eat sweet potato skin? No. The skin should always be removed before serving. Sweet potato skins can be difficult to digest and contain oxalates, which in large or frequent amounts may contribute to increased thirst, tremors and, over time, kidney stress. Stick to plain, cooked, peeled sweet potato flesh only. https://www.aspca.org/pet-care/animal-poison-control

How should I prepare sweet potatoes for my dog? Peel the sweet potato, then cook it thoroughly — steaming, boiling or baking without added seasonings, butter, salt, sugar or spices are all fine methods. Once cooked and cooled, you can cut it into bite-size pieces appropriate for your dog's size, or mash it plain as a food topper. Never add garlic, onion, nutmeg or sweeteners like xylitol, all of which are harmful to dogs. https://www.aspca.org/pet-care/animal-poison-control

Are sweet potatoes safe for dogs with diabetes or weight concerns? Sweet potatoes have a relatively high natural sugar content, which means dogs managing diabetes, obesity or other metabolic conditions may need stricter limits — or should avoid them altogether. Because dogs are omnivores with varying nutritional needs, what's appropriate varies significantly by individual health status. https://www.merckvetmanual.com/management-and-nutrition/nutrition-small-animals/nutritional-requirements-of-small-animals Always consult your veterinarian before introducing sweet potatoes if your dog has any underlying health condition.

Are sweet potatoes found in commercial dog foods? Yes. Many Association of American Feed Control Officials (AAFCO)-compliant dog foods include sweet potato as an ingredient, valued for its dietary fiber and nutrient profile. If you see sweet potato listed on a dog food label, it has been incorporated as part of a formulated, balanced diet — which is different from feeding additional sweet potato as a treat on top of a complete food. Check the ingredient list and consult your veterinarian if you have questions about your dog's current diet. https://www.aafco.org/consumers/understanding-pet-food/

Frequently Asked Questions

Can dogs eat sweet potatoes every day? Sweet potatoes are nutritious, but they are relatively high in natural sugars and fiber. Feeding them daily — even in small amounts — can contribute excess calories and may cause loose stools over time.

Why can't dogs eat raw sweet potatoes? Raw sweet potatoes contain solanine, a naturally occurring compound that can cause vomiting, diarrhea, lethargy and weakness in dogs.

Always cook sweet potato thoroughly and remove the skin before offering it to your dog. https://www.aspca.org/pet-care/animal-poison-control

Are sweet potato skins safe for dogs? No. Sweet potato skins should always be removed before serving.

When in doubt, consult your veterinarian, especially if your dog has any existing kidney concerns. https://www.merckvetmanual.com/management-and-nutrition/nutrition-small-animals/nutritional-requirements-of-small-animals

Can dogs with diabetes eat sweet potatoes? Sweet potatoes have a relatively high glycemic index and contain natural sugars that can affect blood glucose levels. If your dog has been diagnosed with diabetes or insulin resistance, speak with your veterinarian before introducing sweet potato — even as an occasional treat. Your vet can help you determine whether and how much is appropriate for your dog's specific condition. https://sites.tufts.edu/petfoodology/

Do commercial dog foods use sweet potatoes? Yes. Many Association of American Feed Control Officials (AAFCO)-compliant dog foods include sweet potato as an ingredient because it provides dietary fiber that supports healthy digestion. If you see sweet potato on a dog food ingredient label, it has been processed and portioned appropriately for daily feeding — which is different from adding home-cooked sweet potato on top. https://www.aafco.org/consumers/understanding-pet-food/

What should I do if my dog eats sweet potato skin or a large amount of raw sweet potato? Contact your veterinarian or the ASPCA Animal Poison Control Center right away. While a small accidental nibble may cause only mild digestive upset, larger quantities of raw sweet potato or skin — particularly in small dogs — can cause more significant symptoms. Don't wait for symptoms to appear before reaching out to a professional. https://www.aspca.org/pet-care/animal-poison-control
