Can dogs eat popcorn?

Caution — plain air-popped only

Plain air-popped popcorn is safe in small amounts. Buttered, salted, or sweetened popcorn is not.

The full picture

Plain, air-popped popcorn is fine as an occasional treat — it's essentially just a puffed grain. The issues come from what we add to popcorn: butter, salt, sugar, and flavourings are all problems for dogs. Cinema-style popcorn, sweet popcorn, and toffee popcorn should all be avoided. Also watch for unpopped kernels ('old maids') — they're a choking hazard and can damage teeth. If sharing a bowl, pick out only the fully-popped plain pieces.
