Can Dogs Eat Cornstarch?

There are a lot of debates on what to do when dogs eat cornstarch. Some people say that it is okay because it is not toxic, while others believe that it can cause problems like gas and bloat.

Dogs generally love cornstarch because of its sweet taste. While store-bought brands usually have some form of cornstarch listed as an ingredient, there’s no need to worry if your dog ingests a little bit of the powdery substance here and there. However, too much cornstarch can cause gastrointestinal issues in dogs.

In this post, we’ll explain what to do if your dog eats cornstarch and how to keep them safe. Stay safe and keep your dog healthy!

Is Cornstarch Harmful to Dogs?

Dogs are not supposed to eat a lot of pure powdered cornstarch. It could cause digestive issues and respiratory irritation in your dog.

Cornstarch is a common food additive that can be found in many different processed foods. It is a type of starch that is made from corn. It is used as a thickener in sauces and soups, and as a filler in bread and other baked goods. In fact, if your dog is allergic to corn, cornstarch will make the problem worse.

Although cornstarch in baked or dehydrated dog treats is safe for your dogs, overfeeding these treats increases their chances of obesity alongside several different types of heart-related problems.

There is no definitive answer, as cornstarch has not been studied extensively in dogs. However, some people believe that cornstarch can be harmful to dogs because it is a high-glycemic food. Dogs who consume large quantities of cornstarch may be at risk for developing diabetes or other health problems. So, make sure you monitor how much food/fluids are contained within them!

What Are The Side Effects of Cornstarch in Dogs?

Corn starch is a common food ingredient, often used as a thickening or binding agent. It’s also found in many processed foods, such as crackers, cereals, and baked goods. While corn starch is safe for people to eat, it can be problematic for dogs.

What Should We Do When Dogs Eat A Lot Of Cornstarch?

1. Check how much cornstarch your dog consumed

Try and figure out if your dog is eating too much cornstarch in the first place. This can be done by checking the ingredients list on the food packaging or talking to your vet. If it turns out that your dog is eating too much cornstarch, there are a few things you can do to help them out.

2. Access to plenty of freshwaters

Step two is to make sure that your dog has access to plenty of freshwaters. This will help them stay hydrated and will also help flush the cornstarch out of their system.

3. Feed your dog smaller meals

Step three is to feed your dog smaller meals more often throughout the day instead of one large meal. This will help them digest the cornstarch better and will also help keep them from getting too full.

4. Keep an eye on your dog’s stool

If it starts to become loose or watery, it may be a sign that they’re having trouble digesting the cornstarch. If you notice any of these symptoms, talk to your vet as soon as possible.

Most times having cornstarch in dog treats isn’t bad for your dog but do they really provide any health benefits to your furry buddy?

What Are The Benefits of Corn Starch in Dogs?

When used in moderation, corn starch can be a healthy part of your dog’s diet. It’s a good source of fiber and essential nutrients, such as vitamins A and B. Additionally, corn starch can help to regulate your dog’s blood sugar levels.

Plus, it’s a low-calorie treat that’s perfect for dogs who are watching their weight. Here are a few ways you can use cornstarch to improve your dog’s health:

1. Soothe an upset stomach

If your dog has an upset stomach, mix a teaspoon of cornstarch with a bit of water to form a paste. Apply the paste to your dog’s gums and let them lick it off. The cornstarch will help to absorb excess stomach acids and settle your dog’s stomach.

2. Relieve diarrhea and constipation

Cornstarch can be used as a mild laxative to relieve both diarrhea and constipation. Mix a tablespoon of cornstarch with water and give it to your dog orally. For diarrhea, the cornstarch will help to absorb excess water in the intestine. The cornstarch will add bulk to the stool and help move things along for constipation.

3. Help with skin conditions

Cornstarch can also be used topically to soothe skin conditions like hot spots, itchy skin, and eczema. Mix a tablespoon of cornstarch with water to form a paste, then apply it directly to the affected area. The cornstarch will help to relieve inflammation and irritation.

4. Provide fiber

Cornstarch is a good source of dietary fiber, which is important for keeping your dog’s digestive system healthy. Fiber helps to add bulk to the stool and promotes regularity. Mix a tablespoon of cornstarch with water and give it to your dog orally.

5. Make a low-calorie treat

If you’re looking for a low-calorie treat for your dog, mix together equal parts cornstarch and water to form a dough. Roll out the dough and cut it into small pieces. Bake the treats in a preheated oven for 10 minutes, then let them cool completely before giving them to your dog.

It’s fine to serve your dog treats made with cornstarch in a moderate amount. They must not be served as a staple diet and should be supplemented with enough protein-rich foods and vegetables. Remember that though these treats are not necessarily harmful, they can cause problems if you feed too much.


Cornstarch is not a nutritious option for dogs but is still safe when served in a small amount. It is a safe, nutritious addition for dogs when it’s present in baked food. However, your dogs may develop an allergy to corn, make sure you read labels carefully and purchase from brands that do not contain any corn.

Keeping a close eye on what your dog consumes is important for their safety and happiness. I recommend that you contact the vet to ensure any new food items are safe, nutritious but also healthy enough in order not to cause illness or discomfort when consumed by them. This will help ensure both your’ as well as theirs’ long-term wellness!
