Can dogs eat popcorn with no butter and salt?

Yes, dogs can eat plain popcorn without butter and salt in moderation. Plain popcorn is generally safe and can serve as a low-calorie treat rich in fiber. However, it's important to ensure that the popcorn is fully popped and free of any unpopped kernels, which can pose a choking hazard. Always introduce new foods gradually and consult your veterinarian if you have concerns about your dog's diet.
