That’s not a cut and dry answer to give. There is a bit more to it.
Technically red tomatoes are harmless to most dogs. Some dogs do show sensitivities to tomatoes and its best to keep them out of their diet.
Tomatoes are in the nightshade family of vegetables, which means the plants contain a few components that are harmful to certain animals, one of those components are solanine.
Solanine, a substance found in the stem and leaves, the green parts of the tomato and related plants such as the potato, is harmful to dogs in large quantities.

Luckily for dogs that enjoy the occasional tomato, solanine is mostly concentrated in the green parts of the tomato plant.
The leaves, stems, and young, green tomatoes contain higher amounts of solanine than ripe fruit, which means that ripe tomatoes are generally safe to feed to dogs.
This is still problematic for those of us who keep a tomato plant in the garden, as we have to worry about our dogs eating green tomatoes or chewing on the stem and leaves.
I love Green houses because they protect plants against the weather some pests and your animals but also give you the head start in the spring!
Good garden fencing is also a great option when trying to protect your plants and your pets from each other.
Most dogs don’t ingest enough tomato plants to cause a problem but it can cause some discomfort if any green parts are ingested.
Gastrointestinal upset is the most frequently seen symptom of tomato poisoning in dogs.
If you witness your dog eat a green part of a tomato or potato plant, or any other poisonous plants, consult with your veterinarian ASAP.
Symptoms of toxicity:
- Loss of appetite
- Gastrointestinal upset
- Behavioral change
- Dilated pupils
- Abnormal heart rate
Usually, eating a large amount of the green parts of the plant or tomato would be needed to have an adverse affect on your dog. Smaller dogs and puppies may feel the effects after eating a little bit could be toxic.
Always keep an eye on your pets and children around these plants.
