Can Dogs Eat Popcorn? Plain vs Buttered

By Tailwisp Editorial TeamUpdated October 17, 20263 min read

Movie night naturally includes popcorn, and a hopeful dog is often nearby. A piece or two of the plain stuff is not a problem. But the toppings and unpopped kernels are another matter.

Is plain popcorn safe?

Plain, air-popped popcorn is a whole grain, low in calories and contains some fibre. It is not toxic to dogs. Popped corn offers little nutritional value, though, and should be treated as a snack. See our guide to healthy dog treats.

The problem with toppings

• Butter and oil. High fat can upset stomachs and trigger pancreatitis in susceptible dogs. See table scraps and fatty foods.
• Salt. Salty popcorn contributes sodium, which can be a concern in large quantities. See salt poisoning in dogs.
• Caramel and sugar coatings. High in sugar, sticky and bad for teeth.
• Cheese flavorings, which may contain onion or garlic powder. See onions and garlic.
• Chocolate-covered popcorn. Chocolate is toxic. See chocolate toxicity.
• Artificial sweeteners, some of which, such as xylitol, are dangerous. See xylitol.

Kernels and hulls

Unpopped or partly popped kernels are hard and can crack teeth. They can also be a choking risk, particularly for small dogs. Hulls, the thin shell fragments, can lodge in the teeth and under the gums, causing irritation and sometimes infection. Check popcorn carefully, and remove any hard bits before sharing.

How much?

Treats should be no more than about ten percent of daily calories. Popcorn is light, so portions look bigger than they are. A few pieces suit a small dog, and a small handful a large dog. Too much can cause gas or loose stools.

How to prepare

1. Air-pop the kernels, or use plain stovetop popping without oil or with a very small amount of plain oil.
2. Leave out salt, butter and seasonings.
3. Let it cool.
4. Remove unpopped kernels.
5. Offer a few pieces.

Dogs that should avoid popcorn

• Dogs with pancreatitis. See diet for pancreatitis.
• Dogs with dental problems.
• Dogs prone to choking.
• Dogs with corn allergies, though these are rare.
• Overweight dogs, unless calories are counted.

Microwave popcorn

Microwave bags often contain butter flavorings, salt and chemicals. Do not share. Keep bags away from dogs, since eating the bag can cause digestive problems.

Safer crunchy alternatives

Try carrot slices, apple slices without seeds or green beans. See carrots and apples.

Choking and dental safety

Popcorn is light and fluffy, which makes it easy to inhale or gulp. Small dogs and flat-faced breeds can choke if they snatch pieces from the air. Hand-feed a few at a time, and avoid throwing it for catching games. If your dog eats a lot of hulls or kernels, watch for coughing, pawing at the mouth, bad breath or reluctance to eat, and see your vet if signs persist.

Movie night tips

Keep your bowl out of reach, because dogs will happily help themselves from a low table or lap. Set aside a small portion of plain popcorn for your dog before you add toppings to yours. Better still, give your dog its own chew or puzzle toy so it has something to do while you watch the film.

Whole grain and nutrition

Popcorn is technically a whole grain, but the fibre and nutrients are minor compared with a balanced dog food. It is fine for variety, but a small piece of carrot or a few green beans offers similar crunch with extra vitamins for the same calories.

The takeaway

A few pieces of plain, air-popped popcorn are fine. Skip the butter, salt and flavorings, and watch for kernels.
