Is Tomato Plant Toxic to Dogs and Cats? (2026)

Ripe, red tomato fruit is considered safe in small amounts — the concern is specifically green fruit, leaves, and stems, following the same ripeness-dependent pattern as other nightshade-family plants.

The toxic component in Tomato Plant is solanine, concentrated in the green (unripe) fruit, leaves, and stems.

Part-specific risk: Ripe red fruit is much lower in solanine than green fruit, leaves, and stems.

Ripe, red tomatoes are a genuinely common and low-risk treat for dogs in small amounts — the real caution applies to the green, unripe fruit and the leafy vine itself, which share the same ripeness-dependent solanine pattern seen throughout the nightshade family.
