Ripe Only — Avoid Green Parts

Can St. Bernards Eat Tomatoes?

Ripe, red tomato flesh is generally safe for dogs in small amounts. However, the green parts of the tomato plant (stems, leaves, and unripe green tomatoes) contain solanine and tomatine, which are toxic.

🐕 St. Bernard-Specific Guidance

St. Bernards are a giant breed (120–180 lbs), so they can tolerate slightly larger portions, but moderation still applies.

St. Bernards are at risk for bloat (GDV). Avoid feeding large amounts of any new food at once, and don't give treats right before or after exercise.

Nutrition Notes

Ripe tomatoes contain lycopene, vitamin C, potassium, and folate. Low in calories.

Serving Guidance

Only feed ripe, red tomato flesh in small quantities. Remove all stems, leaves, and green parts. 1–2 small pieces as an occasional treat. Avoid tomato sauce (often contains garlic and onion).

Risks to Know

Green tomatoes, stems, and leaves contain solanine and tomatine, causing gastrointestinal distress, lethargy, weakness, and confusion. Keep dogs away from tomato plants in gardens.
