Can Dogs Eat Cornstarch? 11 Hidden Facts

Cornstarch, derived from the corn kernel’s endosperm, is a versatile food ingredient. In baked goods like dog treats, it serves as a thickener, anti-caking agent, and filler.

Cornstarch is made by removing the hull from processed corn kernels and then grinding the endosperm into a powder.

Many factors, such as the availability of cornstarch and the dog’s susceptibility to corn allergies, should be considered before deciding whether or not to feed it to the canine companion.

Pure, powdered cornstarch isn’t toxic, but it’s still not good for your dog, and it may lead to vomiting, diarrhea, and breathing difficulties.

Even though the cornstarch in baked or dehydrated dog treats is safe for your dogs, remember that overfeeding these treats can increase the risk of obesity, cancer, and heart-related problems in canines.

Cornstarch has been shown to be less of a problem for dogs with allergies than corn flour due to its low protein content, which is another concern among dog owners.

Most of the time, Fido is able to digest cornstarch just fine. However, if he begins to exhibit allergy symptoms such as vomiting, diarrhea, or itchiness, a trip to the vet is in order.

Can Dogs Eat Cornstarch?

Dogs can safely eat cornstarch. A certain extent, yes. Don’t wait to call the vet if your dog shows signs of distress after eating cornstarch.

It would be ideal if you could convince them to give it up altogether. In dogs with a corn allergy, cornstarch can bring on anaphylactic symptoms.

Is cornstarch safe for dogs to eat?

Dogs can safely consume small amounts of cornstarch. It’s also found in some dog food formulas.

By contrast, Fido benefits very little nutritionally from cornstarch.

To prevent your dog’s food and treats from getting stuck together, and as a filler.

In any case…

Some canine digestive systems are sensitive to the effects of raw cornstarch.

They won’t eat it unless it’s cooked and mixed in with their dog food.

As with humans, dogs can experience irritation in their eyes and noses if they ingest raw cornstarch. This is why it’s not a good idea to let your dog snack on cornstarch straight from the box.

However, dogs enjoy eating cornstarch.

There were even reports of their use in canine gravy and treats.

Never give your dog an excessive amount of scraps from the table or any other source.

Too much of anything is always a bad idea, but it’s impossible to have too little.

Health Benefits In Cornstarch For Dogs

Cornstarch has a lot of carbs, but dogs don’t need a lot of carbs, and it’s also low in protein, fiber, fat, vitamins, and minerals.

Because cornstarch is a refined food product, it cannot provide the same benefits to dogs as whole corn would.

To keep your dog healthy, you shouldn’t just give them a lot of food, but rather a diet that’s packed with vital nutrients. If you follow these steps, they will become physically robust and formidable.

One cup of cornstarch (128 grams) has the following nutrients, according to the SELF NutritionData database.

  • Powered by: 488
  • Total carbohydrate content comes in at 117g.
  • 1.2% of your daily fiber needs met
  • The weight is 0.3g (grams).
  • Fat: 0.1g
  • Additional Nutrients: 0.5mg
  • Minerals have a 42.8mg DV, or Daily Value.
  • Ten and seven milligrams of liquid

Moreover, cornstarch does not contain gluten, making it suitable for dogs with celiac disease and gluten intolerance.

Due to the increasing number of people who choose to avoid feeding their dogs grains that contain gluten, the demand for gluten-free dog food continues to rise.

Cornstarch has been found to play an essential role in the grooming of dogs.

Is Cornstarch Bad For Dogs

Although feeding your dog cornstarch probably won’t harm him, doing so isn’t ideal because of the lack of essential nutrients.


Cornstarch is frequently used as a filler in dog treats. Even though corn is often used as a filler in dog treats, the inclusion of the corn’s nutrient-rich and fibrous layers makes this misconception false.

Dog treats are a fun way to show your pet some appreciation, but they are no substitute for feeding your dog a nutritious, balanced diet.

Cornstarch contains very little protein, but it may still be too much for your dog to handle.

In spite of the fact that your dog may have been eating the same thing without incident for years, you should always consider the possibility of an allergy.

This happens because the allergen causes a reaction in their immune system, which has become sensitized over time.

Dogs’ allergies are commonly triggered by zein, a protein found in corn.

Corn allergy in dogs results in symptoms that are similar to those caused by other allergens.

  • Vomiting
  • Diarrhea
  • Sneezing
  • Coughing
  • Self-Licking Irresponsibility
  • Eye strain and irritation
  • Discomfort in the Stomach
  • Itching

Even if they contain cornstarch, the vast majority of dog treats are perfectly safe, but are they actually good for your dog?

Do Dogs Like Cornstarch?

Dogs find cornstarch-based treats to be equally appetizing as those made from other ingredients. In fact, they are fantastic incentives for teaching your dog basic manners. Still, cornstarch powder alone is no way to nourish your pet.

If you discover that your dog is eating pure cornstarch, it’s possible that he or she has developed a condition known as pica.

Taking your dog to the vet if you’re concerned about any unusual behavior in regards to eating is a good idea.

How To Feed Your Dog Cornstarch

Never feed your dog cornstarch straight from the box.

Your dog may experience the same sneezing and coughing that you do if exposed to this irritant.

See what happens if you accidentally feed cornstarch to a dog in this video.

The cornstarch in dog treats doesn’t have to make up a huge portion of the treat, though.

Protein-rich foods and leafy greens should be served alongside them, but not as the main course.

Remember that indulging in a few sweets now and then probably won’t cause any major problems, but doing so frequently could be problematic.

3 dangers when your dog eats (too much) cornstarch


Proteins in food tend to trigger allergies in dogs.

They can also be triggered by corn and other sources of simple carbohydrates.

Dogs can actually suffer from corn allergies.

Cornstarch, being a byproduct of corn, can also cause an allergic reaction in Fido.

Sometimes it takes a while for the symptoms of a corn allergy to manifest.

Canine pets are safe to be around corn fields.

However, if your dog eats anything containing even a trace amount of corn, it can have a fatal reaction quickly.

In the case of a corn allergy, skin reactions and other symptoms would present themselves quickly.

Note the following:

  • Hives.
  • Vomiting.
  • Diarrhea.
  • The irritation of the skin has become apparent.
  • Constant licking.
  • There is a focus on the face and the areas around the eyes, which are rubbed.

You should take your dogs to the vet if you notice any of these symptoms.

Be sure it’s a corn allergy, though.

The study found that cornstarch is less likely to trigger allergic reactions in people with corn sensitivities than cornflour.

The fact remains, though, that prevention is always preferable to correction.

Health and sugar level

Cornstarch has high calorie, carbohydrate, and glycemic load values.

It’s missing major nutrients, though.

Are you conscious of that?

Cornstarch has a higher glycemic index than corn. The glycemic index (GI) of a food or drink reveals how much sugar it has.

The glycemic index of corn is 52, while that of cornstarch is 97.

Since the corn’s sugar content would rise in direct proportion to the degree of grinding, this is the case.

When Fido eats cornstarch, his blood sugar level may spike quickly.

The high calorie content also has no bearing on weight control.

Worsening the situation even further.

You probably already know that a diet high in carbohydrates, cholesterol, or sugar is unhealthy for your dog.


When you overeat, your stomach always feels bad.

Overfeeding a dog on cornstarch can also cause stomach problems.

That’s a surefire recipe for gas, tummy trouble, and tummy worms for your canine companions.

You shouldn’t worry if your dog is only showing mild symptoms.

If your dog has stomach trouble, you should wait it out.

To wit: put off feeding your dog for a while.

And wait until Fido has passed all the undigested starch from his system.

Even more so, Vetericyn suggests supplying ice chips.


For the reason that severe cases of either can cause dehydration if they persist for long enough.

There can be too much water, however.

To remedy this, simply replace the ice with water.

Offer your dog some from the bowl every few hours.

If they are able to keep it down, reduce the amount of water they are drinking to sips instead.

PetMD also recommends eating 100% pure pumpkin to aid in digestion.

Since it has a low glycemic index, it won’t upset your stomach as you digest it.

Choose only 100% pure canned pumpkin to guarantee the safety of your recipe.

Learn from the packaging. The use of any sweeteners or other additives is strictly forbidden.

But if Fido’s health keeps deteriorating,

Consult your local veterinarian if you need help.

Due to the risk of pancreatitis and obesity, it should not be given to dogs.

Exposure to any of these diseases poses a significant danger to your dog’s health.

Cornstarch is frequently used as a filler and a source of carbohydrates in dog food.

Dog food companies prefer it because it has a low cost per calorie.

There is, however, another possibility…

While rarely seen, corn allergies in canines do manifest themselves.

And among corn products, cornstarch is the least likely to trigger an allergic reaction.

A better texture in dog food is another benefit of using cornstarch.

Ever since then, it has become standard practice for kibble manufacturers to include it in their formulations.

Contrary to popular belief, cornstarch is used for more than just dog food.

Some dog owners choose to make their own dog food, and cornstarch is a common ingredient.

Fido’s hot spot can be treated with cornstarch three or four times daily.

Also, whenever you notice it seems damp, which could be at any time.

The itching is reduced and the recovery time is shortened.

Don’t stop doing this until the wound has formed a scab and has healed.

Dogs are not likely to develop an allergy to cornstarch. But it’s possible they have a corn allergy.

The causes of food allergies in cats and dogs were studied.

Thirteen of the 297 dogs in the study showed allergic reactions to corn.

Cornstarch can also cause reactions in people who are allergic to corn.

Canine allergy testing is notoriously imprecise.

Since dogs’ immune systems are susceptible to developing sensitivities to the same allergens as people’s, it’s important to avoid exposing them.

Unfortunately, there isn’t a surefire way to tell which dogs have food allergies.

The best treatment option is a trial of eliminating specific foods from the diet.

Veterinarian consultation is highly suggested prior to performing this test.

Dogs with a corn allergy may experience symptoms if they consume large amounts of corn or corn-based products.


Can Dogs Eat Corn Flour?

Although corn flour is widely used as a filler in dog food, it is not a good option due to its lack of nutritional value.

Also, some dogs may be sensitive to this because corn flour is even more allergenic to dogs than cornstarch. So, it’s best to keep Fido away from corn flour.
