Is sweet potato healthy for dogs? What are the benefits of sweet potatoes for dogs?

As mentioned above, sweet potatoes offer the same health benefits to dogs as they do to humans. 

Since dogs do not have much dietary fiber, sweet potatoes can give them that boost they need to keep everything running smoothly. 

Fiber can help lower the risk of heart disease and certain types of cancer. 

On top of that, whole foods do not commonly cause autoimmune responses. In layman’s terms, unprocessed foods don’t usually cause an allergic reaction. 

However, in rare cases, some dogs may have an allergy to certain foods. While true food allergy is rare, you should always keep an eye on your dog whenever you offer them new food. 

Sweet potatoes are high in sugar but low in fat. Diabetic dogs should avoid this tasty treat due to its high glycemic index, as it could raise your dog’s blood sugar.

However, it is rich in vitamins and minerals, each of which has its own benefits to the dog’s body.

Orange-colored vegetables are filled with the antioxidant beta carotene, which can aid the development of vitamin A, which is helpful in both muscle, eye, and cognitive function development and maintenance. 

There is also ample vitamin C to keep the immune system strong, along with trace amounts of calcium, iron, potassium, vitamin B6, manganese, and magnesium.

Iron and vitamin B6 keep red blood cells healthy and functioning. Sweet potatoes have almost the same amount of potassium as bananas, with 337 mg of potassium per 100 grams, whereas bananas would have 358 mg.

Potassium helps optimize muscle, kidneys, and heart function. As for magnesium, it is key in helping your dog convert energy.

According to the USDA, one medium baked sweet potato with skin contains:

  • 103 calories
  • 2.29 g of protein
  • 23.6 g of carbohydrates
  • 0.27 g of fat
  • 3.8 g of fiber
  • 7.39 g of sugar

When is Sweet Potato Harmful to Dogs? 

Raw sweet potatoes or feeding sweet potatoes in abundance may cause health problems to your pup. Excessive carbohydrates can cause obesity, chronic bowel disease, diabetes, organ failure, and even cancer.

Dogs with regular yeast infections should also avoid too much sweet potato as yeast feeds off glucose and would very likely trigger an infection.

There have been certain studies linking grain-free dog food to dilated cardiomyopathy (DCM), which causes the heart to enlarge and may be fatal in some cases.

It is worrying to some dog owners because many grain-free dog food either feature peas or sweet potatoes as a substitute for grains. 

The studies looked at breeds that did not have a predisposition to DCM, and the researchers discovered that 93% of them were on grain-free diets with lentils or potatoes as a primary ingredient

As there isn’t any solid evidence pointing to sweet potatoes as the culprit, and bearing in mind that kibbles are fed on a daily basis, one occasional sweet potato treat is unlikely to be substantial enough to trigger DCM, which is largely a hereditary disease.
