Can Dogs Eat Microwave Popcorn?

A Saturday night is the best time to curl up on your couch with a large bowl of microwave popcorn and watch that movie everyone has been raving about.

Just stick a bag of popcorn in the microwave for a minute and indulge.

Your furry friend may want a bite of your delicious popcorn, and you aren’t sure if it’s safe.

So, can dogs eat microwave popcorn?


Microwave popcorn contains preservatives and unhealthy forms of fat that are harmful to dogs.

The unhealthy fats can cause digestive issues to your dog, while the salt in the popcorn can lead to sodium poisoning leading to dehydration and kidney damage.

Let’s look into why microwave popcorn is not the ideal snack for your dog, what to do if your furry friends ingest microwave popcorn and better alternatives for a snack.

Why is microwave popcorn harmful to your dog?

Air-popped, plain, saltless, butterless, and sugarless popcorn isn’t toxic, but it’s not appealing either.

It’s, however, the only kind that is safe for your canine to eat.

Even when all those factors are considered, your fur buddy can’t ingest more than a few pieces, which have no nutritional value. 

You are also less likely to eat plain saltless popcorn and will have flavors and additives like salt, butter, and caramel, making the microwave popcorn unhealthy for dogs.

Harmful components in microwave popcorn for your dog

High levels of sodium

High salt levels in dogs can be fatal and cause sodium poisoning.

Sodium poisoning causes dehydration, confusion, difficulty breathing, fast heartbeat, and fainting in dogs.

Signs of salt poisoning to look out for are:

  • Vomiting
  • Diarrhea
  • Weakness
  • High fever
  • Increased heart rate
  • Muscle spasms
  • Stomach aches
  • Nausea
  • Loss of appetite
  • Lack of appetite
  • Extreme thirst
  • Frequent urination
  • Confusion
  • Convulsions
  • Coma

Call your vet immediately if your furry friend has gobbled up a bowl of salty microwave popcorn and you notice the symptoms.

High trans fat levels

Many brands of microwave popcorn are made with hydrogenated and partially hydrogenated oils.

Hydrogenated oils contain trans fats, which are harmful to your dog.

Trans fats cause an increase in blood concentration leading to a higher chance of your dog getting heart disease.

Trans fats also interfere with your dog’s glucose and insulin functions.

May contain diacetyl

Microwave popcorn may have additives like artificial butter or caramel containing diacetyl.

Diacetyl is a lethal chemical to dogs as it damages the respiratory system and causes lung disease.

Symptoms to look out for are:

  • Difficulty in breathing
  • Coughing
  • Shortness of breath
  • Fever
  • Irritation on the skin, nose, mouth, and eyes

Perfluorooctanoic acid (PFOA)

Most prepackaged microwave popcorn bags are lined with perfluorooctanoic acid (PFOA), a harmful chemical to your dog.

Extended exposure to PFOA can damage your dog’s immune system and cause liver and kidney diseases.

Popcorn bags are also a potential choking hazard for your dog.

PFOA also increases the risk of certain cancerous tumors.


Other additives like caramel, chocolate, or sugar for sweet microwave popcorn are harmful to your dog.

Flavored popcorn, especially caramel and sweeteners, may contain xylitol which is lethal to dogs.

Chocolate is also toxic in dogs, while sugar can cause obesity and diabetes and further harm your dog’s teeth.

Symptoms of xylitol poisoning are:

  • Weakness
  • Lethargy
  • Low blood sugar 
  • Reduced activities
  • staggering
  • Seizures
  • Collapse
  • Tremors

Symptoms of chocolate poisoning are:

  • Diarrhea
  • Vomiting
  • Increased heartbeat
  • Restlessness
  • Extreme thirst
  • Panting

Risks of microwave popcorn on your dog

Damage to the gums

Unpopped kernels of popcorn can hurt your dog’s gums and chip the teeth causing dental problems.

The microwave popcorn hulls can get stuck between your dog’s teeth, causing discomfort and damage to the gums.

Choking hazard

Whole or partially popped microwave popcorn is a choking hazard.

The unpopped kernels can also cause blockage of your dog’s digestive system.

Gastrointestinal issues

Sweetened or seasoned microwave popcorn can cause digestive problems.

Your dog may react badly to the butter or caramel, leading to effects like diarrhea, vomiting, and dehydration.

Excessive salt can cause kidney damage.
