Can dogs eat tomatoes?

They may be number one in the homegrown garden, but can we share the many benefits of this popular and versatile fruit with our canine companions? Can dogs eat tomatoes? The simple answer is yes; dogs can eat the ripe fruit in moderation.

Nutritional benefits of tomatoes

Tomatoes are widely known for their antioxidant properties. Since there are hundreds of varieties to choose from and easy to grow, it’s no surprise that they are a popular choice for the home vegetable garden.

Tomatoes are a good source of vitamin C, potassium, and folate. They are also one of the major sources of the antioxidant lycopene, linked to the reduced risk of cancer and heart disease. Not only that, but they are a good source of fiber that supports a healthy digestive system.

With so much going for it, it’s no wonder we want to share the benefits of tomatoes with our dogs.

How to feed tomatoes to your dog

Many dogs love tomatoes and will happily eat them raw. However, cooked tomatoes are also fine for dogs. As with any food, though, if you haven’t given your dog tomatoes before, start with a small amount. Monitor your dog for any reactions before increasing the amount or frequency.

The good news is that allergic reactions to tomatoes are infrequent. The most common issue is a gastrointestinal upset caused by the increase in fiber. However, look out for any of the following symptoms ;

  • Rashes
  • Scratching
  • Excessive licking
  • Hot or red ears

Tomatoes the risks

Despite being used primarily as a vegetable, the tomato is actually a berry and is therefore classified as a fruit. It belongs to the nightshade or Solanaceae family of plants along with potatoes, peppers, and eggplant. The nightshade family of plants has a reputation for being harmful to dogs, and this status is well deserved as many of them do contain dangerous toxins.

The tomato plant is no exception. While the fruit is fine to feed your dog, the rest of the tomato plant isn’t ok for dogs to eat.

Tomatoes contain two main alkaloid toxins, solanine and alpha-tomatine. These toxins are primarily concentrated in the stems, leaves, and green tomatoes. Still, they can be found in other parts of the tomato and act as natural defense mechanisms against pests and disease.

Tomatoes have a pungent smell that is off-putting and prickly hairs cover the leaves and stems, making them unpalatable to most animals. However, you should still be cautious as it’s not safe for dogs to ingest any part of the plant, so if you grow them at home, never leave your dog unsupervised or with unrestricted access.

In reality, it would be rare for your dog to experience problems from eating a tomato plant as the amount that they would need to ingest is quite large.

What are the signs of tomato poisoning in dogs?

Solanine poisoning is rare. Dogs would need to eat large quantities of the tomato’s toxic parts for it to cause more than a stomach upset. However, it’s always best to be on the safe side and keep your dog away from tomato plants.

If you’re worried that your dog has eaten a lot of green tomatoes or ingested parts of the plant, they shouldn’t then lookout for any of the following symptoms:

  • Gastrointestinal upset
  • Diarrhea
  • Vomiting
  • Muscle weakness
  • Tremors
  • Difficulty breathing
  • Loss of coordination

Can dogs eat tomatoes?

The good news is that you can feed your dog ripe tomatoes in moderation. The nutritional benefits are huge, and the risk of your dog experiencing any issues is small.

Of course, if you have a dog that will eat anything, the prickly leaves of a tomato plant won’t deter them.  Ensure that you supervise your dog in any vegetable plot, as tomatoes aren’t the only plant with a toxic defense system.
