Can dogs eat asparagus?

Caution — cooked only, raw is tough

Plain cooked asparagus is safe for dogs in small amounts. Raw is too tough to digest. Asparagus fern (the plant) is toxic — keep dogs away.

The full picture

Asparagus is safe for dogs but tricky. Raw asparagus is extremely fibrous and hard to digest — it passes through mostly undigested and can cause GI upset. Cooked asparagus (steamed or boiled plain) is softer and fine in small amounts. It's mildly diuretic, so expect more frequent weeing. Important warning: the asparagus fern — the part of the plant that grows above ground — is toxic to dogs. If you grow asparagus, keep dogs away from the ferns. Skip asparagus prepared with butter, bacon, or lemon.
