Safety guide

Is Tomatoes safe for dogs?

Use with caution

Ripe red tomato flesh is fine in moderation, but green unripe tomatoes, stems and leaves are toxic and sauces are unsafe.

The ripe red flesh of a tomato is non-toxic and safe as an occasional treat in small amounts. The danger is in the green parts — unripe (green) tomatoes, along with the stems and leaves of the plant, contain solanine and tomatine, which are toxic to dogs. Also avoid tomato-based sauces, ketchup and tinned tomatoes, which typically contain onion, garlic, salt or sugar. Keep dogs away from tomato plants in the garden.
