Can dogs eat popcorn?
Plain, air-popped popcorn is generally fine; the butter, salt and unpopped kernels are the issues.
Plain, air-popped popcorn without butter or salt is generally listed as a low-risk occasional treat for dogs. The usual cautions are the added salt and fat on most popcorn, and unpopped or partly popped kernels, which are hard and can lodge in teeth or pose a choking risk.
Classification reflects guidance from VCA, PDSA.
