 Can dogs have tomatoes

Tomatoes, scientifically known as Solanum lycopersicum, are a popular fruit (botanically a berry) from the Solanaceae family, and they’re generally safe for dogs to eat in small amounts—but with some caveats. The ripe, red flesh of tomatoes is non-toxic to dogs and even offers nutritional perks like vitamins A and C, potassium, and antioxidants such as lycopene. These can support a dog’s immune system and overall health, making a nibble of ripe tomato a harmless treat for most pups.

However, the catch lies in the plant itself. Solanum lycopersicum contains solanine, a glycoalkaloid toxin concentrated in the green parts—unripe green tomatoes, stems, leaves, and vines. Solanine can cause gastrointestinal distress in dogs (think vomiting or diarrhea) and, in larger doses, more serious symptoms like lethargy, weakness, or even heart rate changes. The risk is low with ripe tomatoes since solanine levels drop as the fruit matures, but pet owners should steer clear of letting dogs munch on garden plants or unripe fruit.

How much is safe? A small chunk of ripe tomato—say, a cherry tomato or a teaspoon of sauce (without added ingredients like garlic or onions, which are toxic to dogs)—is fine as an occasional snack. But tomatoes shouldn’t be a staple; they’re acidic and could upset sensitive stomachs if overfed. Processed tomato products, like sauces or ketchup, often have salt, sugar, or spices that aren’t dog-friendly, so plain, fresh tomato is best.

Veterinary consensus backs this up: the ASPCA lists ripe tomatoes as non-toxic for dogs, while flagging the green parts as a no-go. Anecdotally, some dog owners toss their pups a tomato slice with no issue, but every dog’s different—watch for allergic reactions or digestive quirks.

Bottom line? Dogs can have ripe Solanum lycopersicum fruit in moderation, but keep them away from the plant’s green bits. If your dog raids the garden, a quick vet check might be wise.
