How much is okay?
If you share tomato at all, use a small piece of ripe flesh only — never garden trimmings.
Rule of thumb: treats of all kinds should stay under ~10% of daily calories.
How to prepare them
- Use only ripe red flesh.
- Remove stems, leaves, and green unripe parts.
- Skip sauces, pizza, and seasoned tomato dishes with onion or garlic.
Risks & exceptions
- Green plant parts and unripe fruit contain solanine.
- Tomato sauces are often salty and seasoned.
- Acidic fruit can upset sensitive stomachs in larger amounts.
Ripe flesh is a tiny occasional; vines, leaves, and green tomatoes are a skip.
If they ate too many
A larger portion or the wrong preparation is most likely to cause trouble.
- Mild stomach upset
Call your vet / pet poison line if:
- Chewing tomato plant leaves
- Repeated vomiting
- Lethargy after plant material
