Plain air-popped kernels (no butter, salt or caramel) are okay in small amounts. Unpopped kernels can damage teeth.
Short answer
Yes, plain air-popped popcorn with no butter, salt, or flavorings is safe for dogs in very small quantities. Make sure to remove any unpopped or partially popped kernels, as they are hard and can damage teeth or pose a choking hazard. This should only be an occasional snack, not a regular part of their diet. If your dog eats a large amount or shows signs of choking or stomach upset, contact your vet.
