🍅 Can Dogs Eat Tomatoes (Ripe vs Green & Vine)?
⚠️ Feed With CautionVeterinary Quick Verdict
Ripe red fruit is safe in moderation. Green tomatoes, vines, and stems are TOXIC.
Health Overview & Veterinary Analysis
Tomatoes belong to the Solanaceae (nightshade) plant family. Green unripened tomatoes, stems, and leaves contain solanine and tomatine, glycoalkaloid toxins that cause cardiac arrhythmias, severe gastrointestinal irritation, and muscle weakness. Fully ripe red tomato flesh contains negligible solanine and is safe in small quantities, but green parts must be strictly avoided.
