  • Whether sweet potato work for dog diarrhea

Let’s get started!

Is Sweet Potato Good for Dog Diarrhea?

Unfortunately, diarrhea is a common affliction in the dog world. As much as we hate to clean a stinky brown puddle after our dogs, diarrhea is a sign that could help us figure out if something wrong is going on with their health.

Causes for dog diarrhea are:

  • Eating toxic food or substances
  • Swallowing a foreign body like a toy
  • Eating a poisonous plant
  • Rapid change in your dog’s diet
  • Allergies
  • Eating too many human foods like greasy food
  • Parasites
  • Virus and bacterial infections
  • Reaction to antibiotics or other medications
  • Stress
  • Serious illnesses, such as kidney, liver, and inflammatory bowel diseases.

You can treat diarrhea at home only when your dog is acting normally except for the diarrhea. If you notice any other symptoms besides diarrhea, you need to call your vet.

So, for mild cases of diarrhea, sweet potato can be your solution. Sweet potatoes are high in fibers, which is great for your dog’s digestive health. Fibers aid your puppy’s digestive system to function better.

If your dog is suffering from diarrhea, it means that the food moves too quickly in his intestines without giving it a chance to absorb the water in it. This results in loose stool, aka diarrhea.

Here’s when sweet potatoes come to your dog’s service. The high fiber content in them helps with water absorption, which slows down the speed at which the stool moves in its intestines.

This way, the intestines have time to absorb the additional amount of water, resulting in a more solid stool.

Sweet potatoes also help with constipation problems and this goes back to its high fiber content as well. Fibers absorb water from the undigested food in the intestines, which helps soften the stool. Therefore, it passes more easily.

You should know that some cases of diarrhea will need much more than just adjustments to your dog’s diet. Your canine friend might need medications in this case.

This is when it’s best to consult your dog’s vet.

Other Benefits of Sweet Potato for Dogs

There are several benefits of feeding sweet potatoes to dogs, which include:

Helps With Obesity

It’s not that sweet potatoes make your dog lose weight. It’s about making him feel full without eating much.

This goes back to the fibers in the sweet potatoes again. Fibers make you feel full without eating much and for a longer period after a meal.

They have the same effect on your dog as well. So, if your dog is struggling with obesity, maybe he can benefit from a diet with high fiber content.

You can add sweet potatoes to his diet to help with that problem. However, it’s best to talk to your dog’s vet first before making that decision.

Provides Plenty of Antioxidants

Sweet potatoes contain plenty of antioxidants that are beneficial for you and your dog. Antioxidants can protect our bodies and our doggies’ bodies against free radicals.

Those free radicals are what cause damage to the DNA, leading to inflammation. This can cause serious illnesses, such as cancer and heart diseases.

Therefore, antioxidants in sweet potatoes can help your dog’s body fight against those serious health problems.

Contains Several Vitamins

Sweet potatoes contain several vitamins, such as:

  • Vitamin A
  • Vitamin C
  • B Vitamins

Vitamin A is essential for all dogs. It promotes skin, coat, muscles, and nerve health.

It’s even more crucial for pregnant dogs and puppies. It helps with the growth and development of muscles and nerves.

Vitamin C is another essential vitamin for dogs. It’s an antioxidant that strengthens your dog’s immune system against free radicals.

The entire group of B vitamins is important to all dogs. They help dog’s bodies perform vital functions, such as facilitating enzyme function, regulating energy metabolism, and generate glucose.

Loaded With Minerals

Sweet potatoes don’t just contain vitamins, but they’re also loaded with different minerals. This includes:

  • Calcium
  • Iron
  • Potassium
  • Magnesium
  • Phosphorus
  • Zinc

All these minerals play a great role in keeping your dog healthy. For example, calcium promotes strong, healthy bone growth. It’s also crucial for your dog’s teeth.

Another good example is iron. It helps with the formation of red blood cells and hemoglobin.

So, if your dog has a deficiency in any of these minerals, sweet potatoes can be a tasty way to help him with that.

What Is the Safe Amount of Sweet Potato Dogs Can Eat?

Although sweet potatoes are extremely beneficial to dogs and provide them with lots of nutrients, you have to feed them to your furry friend in moderation.

Keep in mind that dog bodies are different. What is a lot for them might be moderate for us and vice versa.

So, what is the safe amount of sweet potato that you can feed your dog?

The best thing you can do here is to ask your dog’s vet. Not all dogs are the same, and your dog’s vet will give you the answer that best fits his needs.

However, in general, you can introduce sweet potatoes to your dog’s diet by incorporating not more than an ounce or two per serving.

In the beginning, you can mix sweet potato with his regular dog food, but start first with only one meal. If he tolerates it well, you can continue adding it to his meals.

You can also make some treats for him with sweet potatoes. Keep in mind that treats and toppings shouldn’t make up more than 10% of his daily caloric intake.

For smaller breeds, just a quarter or half an ounce of sweet potatoes per serving is more than enough to start incorporating into their diets.

Be careful, before you start adding sweet potatoes to your dog’s diet, make sure that his kibble and store-bought treats don’t contain sweet potatoes already.

Grain-free dog food specifically contains sweet potatoes listed within the first ten ingredients. If your dog’s regular food contains sweet potato already, you might not need to add more to his diet.

In this case, you should consult your vet. Make sure that you tell him about the type and brand of dog food you give to your buddy.

Can Sweet Potato Be Dangerous for Dogs?

Yes, sweet potato can be dangerous for dogs in some cases. That’s why we always recommend checking with your dog’s vet first before incorporating this veggie into his diet.

Here are some cases where sweet potatoes can be dangerous to dogs:


Dog lying down with diabetes kit and insulin

Sweet potatoes are high in carbohydrates, which are broken down into simple sugars by our bodies. This causes our blood sugar levels to increase.

The same process happens in our dogs’ bodies when they eat sweet potatoes. Therefore, if your dog is diabetic, it’s best to only give him sweet potatoes occasionally as a treat.

However, don’t even start giving him sweet potatoes until you check with his vet first.

Dilated Cardiomyopathy

Dilated Cardiomyopathy (DCM) is a serious health condition where the heart of the dog becomes enlarged.

In this case, the heart becomes unable to pump blood to the rest of the body and fluid accumulates in certain tissues.

How is this heart condition linked to sweet potatoes? In recent years, there have been ongoing investigations around the relation between grain-free dog food and the increase in DCM cases.

While scientists still don’t know the reason behind the increase in DCM cases, it was estimated that a large number of DCM-diagnosed dogs were eating foods containing sweet potatoes.

This doesn’t mean that incorporating sweet potatoes into your dog’s diet will cause DCM. As long as you’re feeding your dog sweet potatoes in moderation, there’s nothing to worry about.

Keep in mind that sweet potatoes and dog food that contain them are not recommended for breeds that are known to have a genetic predisposition to this disease.

These breeds include:

  • Doberman pinschers
  • Great Danes
  • Boxers
  • Cocker spaniels
  • Golden retrievers
  • Labrador retrievers
  • Australian shepherds
  • German shepherds
  • Pit bulls
  • Mastiffs
  • Standard poodles


While sweet potato allergies are uncommon, there’s still a possibility that your dog might have it. When introducing sweet potatoes to your dog’s diet for the first time, it’s important to check for any food allergy signs, such as:

  • Itchy skin and hives
  • Loose stool
  • Ear or paw infection
  • Stomach issues
  • Vomiting

Once you notice any of these signs, call your vet immediately.

What Is the Best Way to Serve Sweet Potato to a Dog With Diarrhea?

It’s most likely that your canine friend will fall in love with sweet potatoes, as most dogs love their taste and aroma.

There isn’t a best way to serve sweet potato to your dog. You can actually incorporate it into his diet in many ways.

No Raw Sweet Potato

Be careful that raw sweet potatoes can upset your dog’s stomach. This is the exact opposite of what we’re trying to do here.

They can also be a choking hazard. So, cooked sweet potatoes are the best here.

Stick With Boiled or Steamed

Sweet potatoes in a steamer

Boiled, steamed, baked, or roasted sweet potatoes are all okay to offer to your dog. However, if you’re worried about his sugar levels, then avoid the last two methods.

Baking and roasting sweet potato destroy its resistant starch, which increases its glycemic index. So, maybe stick to boiled or steamed.

No Spices or Salt

Don’t feed him sweet potatoes that have spices or salt on them. This means you should avoid sharing your sweet potato chips or fries with your dog.

Spices and salt can upset your dog’s stomach. This is also something to consider if you’re serving dehydrated sweet potatoes to your dog.

Fresh Is the Best

Besides all that, it’s best to serve your dog fresh sweet potatoes. Processed or frozen sweet potatoes usually contain preservatives that are not the best for your dog.

Cut Into Small Pieces

Make sure that you cut sweet potatoes into bite-sized pieces so your dog can eat them easily. You can also mash them and mix them with his kibble.

Sweet Potato Kibble or Treats

Lastly, you can feed him dog kibble or treats that contain sweet potato in the ingredients.
