Can Dogs Eat Tomatoes?

Last update:

Can dogs eat tomatoes? We’re here to dish out the juicy details.

The short answer is yes, it’s okay for dogs to eat tomatoes.

However, tomatoes may cause your dog digestive distress, so read on while we separate the myths from the facts.

We’ll discover why a small tomato nibble is normally fine, but caution against tossing a tomato feast their way on a daily basis.

So, grab a tomato (for yourself, not your pup!), and let’s dig into this juicy (dare I say “saucy”??) topic together!

Key takeaways

  • Tomatoes are okay for dogs, but, like anything that isn’t actual dog food, moderation is key.
  • Too much can lead to digestive issues (and nobody wants that!)
  • Any green parts should not be fed to dogs.
  • Dogs can be allergic to tomatoes, so if this is new for your pooch, start very small and watch for warning signs.

Unveiling the Dangers of Tomatine Poisoning

One of the concerns associated with tomatoes is the presence of a substance called tomatine.

Tomatine is found in the stems and leaves of the tomato plant and in green, unripe tomatoes. In large amounts, tomatine can be toxic to dogs. However, the ripe, red flesh of the tomato contains lower levels of tomatine and is generally considered safe for dogs to consume in moderation.

We should note that tomatine is more toxic to dogs than humans. 

This is one of those urban legends that has grown over time as larger grazing animals such as cows and goats gain entrance to tomato patches and eat a lot of tomato plants. In these extreme cases, the animals have ingested so much tomatine that they succumbed to tomatine poisoning. 

It’s worth noting that the number of tomatoes a dog needs to eat to get a fatal dose of Tomatine exceeds their ability to eat without getting sick.

By a lot.

In the source above, the following dog weights and equivalent green tomatoes to affect a dog are shared:

  • 60lb dog would need to eat about 472 green tomatoes to have a 50% chance of dying of tomatine poisoning
  • 30lb dog would need to eat about 236 
  • 10lb dog would need to eat about 78

For comparison, that 60lb dog would need to eat about 56,640 red tomatoes to be in danger of tomatine poisoning. 

These numbers are for green tomatoes when the presence of tomatine is at the highest levels, and red tomatoes contain less tomatine and are less dangerous for dogs. 

Size of dogAmount of Tomatine for lethal dose (Fatal for 50% of subjects)# of Green Tomatoes# of red Tomatoes
60 lb dog2721mg47256,640
30 lb dog1360mg23628,320
10 lb dog453mg789,440
The odds of your dog eating enough tomatoes to prove fatal is extremely unlikely.
Are tomatoes dangerous for dogs?  Turns out, not so much.

So the danger of your dog dying from tomatine poisoning is very slim. However, of course, it takes less to make the dog sick than a human, and this is why we recommend keeping your pup away from green tomatoes and tomato plants and consider feeding it small amounts of red tomatoes when the mood strikes you. 

Also, as always, we here at JollyMutt advocate for feeding dogs very little human food and sticking to the plentiful dog-specific food and treats just to be safe.

Spotting Symptoms of Tomatine Poisoning in Dogs

If your dog has consumed excessive amounts of tomatine, there are specific symptoms you should watch out for. These symptoms may include:

  • Upset stomach
  • Diarrhea
  • Vomiting
  • Lethargy
  • Weakness
  • Abnormal heart rate
  • Difficulty breathing

If you notice any of these symptoms after your dog has ingested tomatoes, it’s crucial to contact your veterinarian immediately. If you cannot reach anybody local, you can use the ASPCA poison control hotline number below:

Tomatoes are generally considered safe for dogs, with minimal toxicity concerns. The likelihood of dogs consuming a harmful amount of tomato plants is low. Tomato plants belong to the Nightshade family and contain a substance called tomatine. Tomatine is most concentrated in leafy greens, fruit blossoms, and unripe green tomatoes, but its levels decrease as tomatoes ripen. Ingestion of stems, vines, or unripe fruit may lead to gastrointestinal irritation, weakness, and ataxia. Treatment for tomato plant ingestion involves supportive care, and the prognosis is typically favorable.

Explore the Benefits of Tomatoes for Dogs?

While tomatoes have risks, they also offer some potential benefits for dogs. Tomatoes are rich in essential nutrients such as vitamins A and C and antioxidants. These nutrients can support your dog’s immune system, promote healthy skin and coat, and contribute to overall well-being.

Some Parts of the Tomato are Dangerous for Dogs

Although the ripe flesh of tomatoes is generally safe for dogs, it’s important to be cautious about other parts of the tomato. The stems, leaves, and unripe green tomatoes contain higher levels of tomatine, which can harm dogs. Remove the stems and leaves, and only offer your dog the ripe, red part of the tomato.

Sharing the Love: Safely Indulging Dogs with Tomatoes

If you want to share a tomato treat with your furry friend, there are a few crucial guidelines to follow:

  • Stick to the ripe, red flesh: Only offer your dog the ripe part of the tomato, free from stems, leaves, and unripe areas.
  • Moderate portion sizes: Tomatoes should be given as an occasional treat and not make up a significant portion of your dog’s diet.
  • Introduce gradually: Start by offering a small amount of tomato and monitor your dog’s reaction. If there are no adverse effects, you can continue to include tomatoes as an occasional addition to their meals.
  • Consult your veterinarian: If you have any concerns about your dog’s specific dietary needs or health conditions, it’s always best to consult your veterinarian for personalized advice.

Tiny Taste Buds – Can Puppies Eat Tomatoes?

When it comes to puppies, extra caution is advised.

Their delicate digestive systems are still developing, and certain foods may not agree with them.

In the case of tomatoes, it’s best to hold off until your puppy is a bit older.

Once they have reached adulthood and their digestive system has matured, you can gradually introduce small amounts of tomatoes into their diet.

Tomato Temptations: Preventing Tomato Overindulgence in Dogs

It’s essential to watch how much tomato your dog consumes. Too much of any food can lead to digestive upset or other health issues. Here are some tips to prevent your dog from ingesting too many tomatoes:

  • Keep tomatoes and tomato plants out of reach: Make sure your dog doesn’t have access to tomato plants or ripe tomatoes in your garden. It’s better to be safe than sorry.
  • Store tomatoes properly: If you have tomatoes in your kitchen, store them in a secure location where your dog cannot reach them. This prevents any accidental ingestion and ensures that you have control over how many tomatoes your dog consumes.
  • Be mindful of tomato-based products: Keep an eye on the ingredients in dog food, treats, or any other products you give to your dog. Some commercial products may contain tomato-based ingredients, such as tomato sauce or soup. While small amounts are generally safe, excessive consumption could lead to digestive issues.
  • Educate family members and visitors: If you have family members or visitors who may not know the potential risks associated with tomatoes, inform them about the guidelines for feeding your dog. This helps create a safe environment and avoids any accidental ingestion of tomatoes.

Can Tomatoes Be Good for Dogs?

When offered in moderation and prepared correctly, tomatoes can provide some health benefits for dogs.

The vitamins and antioxidants found in tomatoes can support their immune system, contribute to a healthy coat, and promote overall well-being.

However, it’s important to remember that tomatoes should only be a small part of your dog’s diet, not a substitute for balanced dog food.

Can Tomatoes Be Bad for Dogs?

While tomatoes have benefits, they can also have drawbacks if not consumed appropriately.

Dogs with certain health conditions, such as kidney problems or gastrointestinal sensitivities, may have difficulty digesting tomatoes.

Excessive consumption or feeding unripe parts of the tomato can lead to tomatine poisoning, causing digestive upset, weakness, and other adverse symptoms.

Tread with Caution: When Tomatoes are bad for Dogs

Tomatoes are particularly risky for dogs when they are unripe or when the stems and leaves are ingested.

Unripe tomatoes contain higher levels of tomatine, which can be toxic to dogs.

The stems and leaves of the tomato plant also contain concentrated amounts of tomatine and should be kept away from your dog.

Are Tomatoes Poisonous for Dogs?

While tomatoes are not inherently poisonous to dogs, certain parts of the tomato plant can be toxic.

As mentioned before, the stems, leaves, and unripe green tomatoes contain higher levels of tomatine, which can harm dogs.

However, ripe tomatoes with removed stems and leaves are generally considered safe in small amounts.

Saucy Dilemma: Can Dogs Lap Up Tomato Soup or Tomato Sauce?

Tomato-based products like sauce or soup can be a bit more complex. Pasta sauce for spaghetti or lasagna falls into this category as well.

These products often contain additional ingredients, such as spices or seasonings, salt, or even garlic, which are unsuitable for dogs.

Moreover, they can be high in sodium or other additives that harm your dog’s health.

It’s best to avoid sharing tomato sauce or tomato soup with your dog, or if you choose to do so, ensure it’s in small amounts and free from any potentially harmful additives.

  • Nutritional variety: Adding small amounts of tomatoes to your dog’s meals can introduce variety and natural flavors, making their meals more enjoyable.

Garden Hazards: Are Tomato Plants Toxic to Dogs?

Aside from the tomatoes themselves, the tomato plant can pose risks to dogs.

The stems, leaves, and unripe green tomatoes of the plant contain higher levels of tomatine, which can be toxic when ingested.

Preventing access to tomato plants is essential to ensure your dog’s safety.

If you have a garden or keep potted tomato plants, ensure they are placed in an inaccessible area to your dog. This reduces the risk of accidental ingestion and potential health complications.

The Telltale Signs: Unmasking Symptoms of Tomatine Poisoning

If your dog consumes excessive amounts of tomatine, it may exhibit specific symptoms indicating tomatine poisoning. It’s important to be vigilant and watch for the following signs:

  • Upset stomach: Digestive issues such as vomiting, diarrhea, or general gastrointestinal discomfort may occur. You may want to give your pup a Tums for an upset stomach.
  • Lethargy: Your dog may appear unusually tired or lacking energy.
  • Weakness: Muscle weakness or difficulty moving may be observed.
  • Abnormal heart rate: Irregular heartbeats or changes in heart rate can occur.
  • Difficulty breathing: Labored breathing or respiratory distress may be present.

If you notice any of these symptoms in your dog after ingesting tomatoes or any part of the tomato plant, it is crucial to seek immediate veterinary assistance. Prompt medical attention can help mitigate potential complications and ensure your dog’s well-being.

  3. Add the pureed tomatoes and water to the bowl and mix well until a dough forms. You may need to adjust the amount of water slightly to achieve the right consistency.

From Fresh to Canned: Can Dogs Savor Tinned Tomatoes?

When it comes to tinned or canned tomatoes, proceed with caution.

Always check the label and opt for plain, unsalted, and unsweetened tinned tomatoes if you decide to share them with your dog.

While the ripe flesh of canned tomatoes is generally safe for dogs, choosing plain varieties without added spices, seasonings, or other harmful additives is crucial.

However, it’s worth noting that fresh, ripe tomatoes are generally a better choice, as canned tomatoes may contain preservatives or other substances that can be less beneficial for your dog’s health.

Can dogs eat other vegetables?


As with tomatoes, this should be done sparingly and should not constitute the bulk of any of your dog’s meals, but veggies such as bell peppers, olives, edamame, or jicama are great snacks for your pup. Again, in moderation.
