Can dogs and cats eat tomato?

Quick verdict for Tomato: see below the answer for dogs and for cats, the symptoms of poisoning (when applicable), and what to do if your pet ate it anyway.

For dogs

In moderation

For cats

In moderation

Why is this the verdict?

Ripe, red tomato, in small amounts, is generally safe: the concentration of tomatine and solanine (potentially toxic glycoalkaloids) drops sharply as the fruit ripens. Green or unripe tomato, and especially the foliage, stem, and the tomato plant itself, contain much higher levels of these substances and are considered toxic.

If you grow tomatoes at home, keep pets away from the plant. When offering tomato, use only ripe flesh, with no stem, in small pieces and occasionally — there's no meaningful nutritional benefit that justifies making it a daily habit.

Symptoms to watch for

Watch for these signs

  • Excessive drooling
  • Vomiting
  • Diarrhea
  • Weakness and tremors (with ingestion of the plant or unripe fruit in quantity)
  • Irregular heart rhythm (rare, severe cases)

What to do if your pet ate it anyway

If it was just a piece of ripe tomato, no action is needed. If your pet ate green parts of the plant, green tomatoes, or a large amount, watch closely and contact a veterinarian if vomiting, diarrhea, tremors, or lethargy appear.
