Are Tomatoes Bad For Dogs?

Vegetables are an indispensable part of our daily diet. Veggies are rich in minerals and vitamins our body needs to function properly. However, just because something is good for us, it doesn’t automatically mean it’s good for our dogs. For example, tomatoes are one of the most common vegetables found in our diet. We all know tomatoes are healthy for us and all the health benefits they bring. However, are tomatoes good or bad for our dogs? Can our furry friends eat tomatoes?

Are Tomatoes Bad For Dogs?

The short answer would be yes, dogs can eat tomatoes. However, there are several things you should keep in mind when feeding your dog tomatoes.

Tomatoes are vegetables from the nightshade family. Therefore, they contain substances that are, in higher amounts, toxic to dogs. 

For example, tomatoes contain solanine. This substance is toxic to dogs. However, solanine is mostly concentrated in the leaves and the stem of the tomato plant and green, young tomatoes.

On the other hand, ripe tomatoes contain far less solanine and are safe for your dog to eat.

Tomatine poisoning is very rare in dogs. However, you need to be careful if you have a garden with tomato plants as your dog may consume leaves or green tomatoes. 

If the dog ate leaves, stem, or green tomatoes, he will exhibit the following symptoms:

  • Muscle weakness
  • Seizures
  • Gastrointestinal issues
  • Loss of coordination
  • Tremors
  • Vomiting
  • Diarrhea
  • Abnormal heart rate
  • Drowsiness

In case you know your dog ate green parts of the tomato plant and notice any of the following symptoms above, call the vet immediately.

Tomatoes can also worsen symptoms in dogs that are already suffering from gastrointestinal issues or acid reflux.

Can Dogs Be Allergic To Tomatoes?

Are Tomatoes Good For Dogs?

So, what exactly is the connection between dogs and tomatoes? Can dogs get any health benefits from eating tomatoes? Tomatoes are low in calories, high in fiber and rich in nutrients. Therefore, tomatoes are good for dogs if consumed in smaller quantities. They are a common snack and meal ingredient for humans due to their low calorie and high fiber content. They are high in the carotenoids lycopene and beta-carotene, which can aid in disease prevention.

Tomatoes also include anti-oxidant vitamins such as vitamin A, vitamin B12, and vitamin C. In the minerals department, they have a lot to offer as well. They’re high in folate, potassium, and chromium. So they’re obviously nutrient-dense. But what are the impacts of these nutrients on our dog’s health?

How To Serve Tomatoes To Your Dog?

Before giving tomatoes to your dog, consult with your vet to make sure it’s completely safe. Dogs get all the needed nutrients through their regular diet, so they don’t really need tomatoes. However, tomatoes can serve as an occasional healthy treat.

Make sure to give your dog only ripe tomatoes without leaves, stems, or vines. Don’t add salt on any other spice to the tomatoes you are planning to give to your dog.

Tomatine is only found in trace concentrations in ripe, red tomatoes. As a result, ripe tomatoes are generally okay for dogs to consume as a treat every now and again. However, because a puppy’s immune system is still developing during the first year of life, you should generally avoid feeding even ripe, red tomatoes to a young dog. 

Are Cherry Tomatoes Safe for Dogs to Eat?

It’s worth noting that grapes are poisonous to dogs, yet grape tomatoes aren’t related to grapes at all!

Are Sun-Dried Tomatoes Safe for Dogs to Eat?

Sun-dried tomatoes are frequently made with ripe tomatoes, so the issue isn’t so much about the tomatoes themselves. However, they are frequently sold packaged in oil or with other ingredients that may be harmful to your dog’s health, such as garlic and other seasonings. Sun-dried tomatoes cooked at home are most likely made from ripe, peeled, organic tomatoes, which should be fine for your dog.

Can Dogs Eat Cooked Tomatoes?

One advantage of eating cooked rather than raw ripe, red tomatoes is that cooked tomatoes deliver the powerful antioxidant lycopene in a form that the body may more easily absorb. So, are cooked tomatoes safe for dogs?

However, make certain that no green or underripe tomatoes were used in the cooking process, as they are poisonous to your dog. Make sure the cooked tomatoes don’t include any additional components that could hurt your dogs, such as sodium, seasonings, or additives.

 What About Canned Tomatoes?

Is Tomato Juice Safe for Dogs?

Again, it’s critical to examine the potential additives in tomato juice to ensure that nothing hazardous to your dog is there. If the tomato juice is created from pure, ripe tomatoes, it should be okay for your dog to drink in little amounts. A dog, on the other hand, is unlikely to swallow much tomato juice. He’ll probably be satisfied with a couple of tongue-laps!

Is Tomato Paste Safe for Dogs?

The worry, as with the tomato sauce, is what may have been added to the paste. If it’s just pure tomato paste made from ripe tomatoes, like in a pizza recipe for dogs, it should be fine in moderation.


Ripe tomatoes are good for dogs if you give them occasionally as a treat. On the other hand, tomato leaves and green, young tomatoes are bad for dogs due to the higher concentration of a toxic substance called solanine.
