Yes, when it is plain. A small amount of fully popped, air-popped popcorn with no butter, oil, salt or sugar is fine as an occasional snack, according to the AKC. The kernels that did not pop are the part to keep away, because they can choke a dog or wedge between the teeth.
If your dog snapped up a few pieces from the floor, there is nothing to do. If they emptied a bowl of buttered or flavored popcorn, or you hear coughing or gagging, read on.
Key takeaways
Tap a card to bring it forward.
- Plain, air-popped popcorn is an acceptable occasional snack.
- Butter, oil and salt can upset a dog's stomach, and a big fatty serving can bring on pancreatitis.
- Unpopped and half-popped kernels can cause choking, lodge in the teeth, or add to a blockage.
- Flavored popcorn needs a label check for chocolate, xylitol, onion or garlic.
- Choking, trouble breathing or swallowing, or vomiting that keeps coming back means a vet now.

How much popcorn makes a sensible treat
There is no piece count by dog size, so think of popcorn as a treat and keep it small. The AKC's general rule is that treats should stay at or under 10% of a dog's daily calories.
- Pop it in an air popper or a dry covered pan, without oil.
- Set your dog's share aside before you add butter or salt to your own bowl.
- Pick out every unpopped and half-popped kernel.
- Give a few pieces at a time, fewer for a small dog.
Air-popped popcorn is low in calories, which is why the ASPCA suggests it as a snack for dogs that need to slim down. Popped corn has some fiber and small amounts of magnesium, manganese, phosphorus and zinc (AKC), but it adds nothing a complete dog food does not already cover. If your dog is on a special diet for kidney disease, diabetes or a stomach problem, ask your vet first.
Signs to watch for after popcorn
- Right away, from a kernel: coughing, gagging, trouble swallowing, signs of a sore mouth, or choking. Choking is an emergency.
- Within hours: gas, vomiting or diarrhea, most often after buttery, salty or large helpings.
- Over hours to days: repeated vomiting, belly pain, not eating or tiredness, which can mean a blockage from kernels or pancreatitis from fat, according to the AKC.
Plain popped corn is not a poison. When a dog gets sick after popcorn, it is usually the kernels, the fat, the salt or the flavoring.
"My dog gets popcorn every movie night and loves it"
That may be working fine. A few plain pieces fit well within the rules, and many dogs get them without trouble. It is still not a rule for every dog or every bowl. A bowl finished with butter and salt is a different food, and the unpopped kernels collect at the bottom where a dog licking the bowl finds them. A small dog gets a much bigger dose of fat and salt from the same handful. And pancreatitis or a blockage can take hours or days to show, so a dog who seemed fine at bedtime may not be fine the next day. Keep your dog's pieces plain and separate.
Corn cobs, corn nuts and other popcorn look-alikes
- Corn on the cob: the cob can cause choking or an intestinal blockage, so never give one, according to the AKC.
- Corn nuts: hard, roasted or fried corn that is often salted. They are tougher on teeth than popcorn.
- Popcorn chicken: breaded meat that can carry salt, fat, onion, garlic or bones.
- "Pupcorn" and dog popcorn treats: a dog-themed label is no guarantee. Read the ingredients like any other snack.
- Chocolate or candy-coated popcorn: the coating decides the risk. Chocolate is toxic to dogs.

Questions about dogs and popcorn
Is microwave popcorn okay for dogs?
It depends on the box. Microwave popcorn can include oil, salt, butter flavoring, sugar or seasonings, so read the ingredients. Plain air-popped popcorn is the better choice to share.
What happens if my dog eats an unpopped kernel?
A kernel can lodge in the mouth or between the teeth, cause choking, or add to a blockage (AKC). Watch for coughing, gagging or trouble swallowing right away, and vomiting or not eating later, and call your vet for any of those.
Can dogs eat buttered popcorn?
Not as a treat. Butter and oil add a lot of fat, which can cause vomiting and diarrhea and may trigger pancreatitis in some dogs.
Can puppies eat popcorn?
The same plain, fully popped popcorn applies, in smaller amounts. Be extra careful to remove kernels, since a small mouth and throat choke more easily.
Can cats eat popcorn?
The ASPCA lists unseasoned, unbuttered popcorn as a snack for cats as well as dogs. The same rules apply: plain, fully popped, no kernels.
