Pocket VetCan dogs eat tomatoes?
⚠️ Caution — conditions applyThe ripe red flesh of a tomato is safe for most dogs as an occasional treat. The risk is the green parts — unripe fruit, stems, and leaves — which contain solanine, and seasoned tomato dishes with onion or garlic.

Frequently asked
Are tomatoes poisonous to dogs?
Ripe tomato flesh is not — it's safe in moderation. The green unripe fruit and the plant's leaves and stems contain solanine, which can upset a dog in larger amounts.
Can dogs eat tomato sauce or ketchup?
Better not. These often contain onion, garlic, salt, and sugar, which aren't good for dogs — stick to a little plain ripe tomato.
