Can dogs eat tomato (ripe)?

In moderation
Only ripe, red tomato flesh in small amounts, and never the green parts of the plant.

Why

Ripe tomatoes are non-toxic and contain fiber, antioxidants, and vitamins C and K. The green parts of the plant, including leaves, stems, and unripe green tomatoes, contain solanine and tomatine, which are toxic to dogs. The acidity can also upset the stomach, and processed tomato products often contain onion or garlic.

How much is safe

Offer small amounts of ripe, red tomato with all green parts removed and the flesh diced.

Warning signs to watch for

Green parts or large amounts can cause gastrointestinal upset, and solanine or tomatine ingestion may cause more serious signs.
