Can dogs eat tomatoes?
CAUTION Category: Vegetable · Source verified September 2026
Ripe red tomatoes are safe for dogs; the danger is in green tomatoes, stems and leaves, which hold solanine and tomatine. A bite of salad tomato is harmless, but garden access to the plant can cause trouble. If you grow tomatoes, fence them off — dogs that chew the vines get the highest doses.
Symptoms to watch for
- gastrointestinal upset
- lethargy
- weakness
- confusion
If you suspect poisoning: call your vet or the ASPCA Animal Poison Control Center at (888) 426-4435 (available 24/7). Do not induce vomiting unless instructed by a professional.
