Will It Poison?

Can Dogs Eat Tomatoes?

Caution

⚠️ Risky — depends on amount & dog

Ripe red tomatoes are fine in small amounts — but the green parts (stems, leaves, unripe fruit) contain solanine, and tomato sauces usually hide onion and garlic.

A slice of ripe tomato is harmless to most dogs. The nightshade toxin solanine lives in the plant's green material — stems, leaves, and unripe green tomatoes — which matters most for dogs with garden access. Sauces, soups, and pizza toppings are a separate problem: they're routinely loaded with onion, garlic, and salt.

What makes it dangerous: Solanine/tomatine (green parts only)

Symptoms to watch for

  • GI upset
  • Drooling
  • Weakness or wobbly gait (large green-plant ingestions)

What to do right now

  1. Ripe tomato flesh: no action needed
  2. Garden plant grazing: remove access and call your vet if weakness or drooling appears
  3. Sauce with onion/garlic: treat as allium exposure

Stop the next one before it happens

Most food poisonings aren't fed to the dog — they're scavenged from a bin, a counter or an open cupboard while nobody's looking.
