Safety Summary

✔ Safe: Ripe red flesh in small amounts
⚠ Use caution: Green parts and unripe tomatoes are toxic
✖ Toxic: Green tomatoes, stems, leaves (solanine)

Why

Ripe red tomato flesh is generally considered safe for dogs in small amounts. However, the green parts of the tomato plant — stems, leaves, and unripe green tomatoes — contain solanine and tomatine, compounds toxic to dogs. Tomato sauce and ketchup should also be avoided due to added salt, sugar, garlic, and onion. When in doubt, skip the tomato.

Portion Guidance

A small piece of ripe red tomato flesh occasionally. Remove all green parts first.

Risks & Symptoms

Green parts/unripe tomatoes: solanine toxicity — vomiting, muscle weakness, tremors
Tomato products: additives like garlic/onion are toxic
Too much: digestive upset from acidity
