Can dogs eat tomato?

THE DOGS AND THE TOMATO The tomato is one of the most used vegetables in the kitchen, either in its natural form or as an ingredient in numerous recipes. When you have a dog at home, it is almost impossible to avoid exposure to tomatoes on a daily basis. But just because a food is good for you, doesn’t mean it’s good for your pet too. Is it safe for a dog to eat tomato? The Big Question Can dogs eat tomato?

Some say yes and some say no. What is the cause of this confusion?

If you still have doubts about it, you will be interested to know that, when it comes to tomato safety in dogs , color is the key.

Can dogs eat raw tomato?

It depends. The tomato or tomato plant belongs to the Solanaceae family, like the potato and the eggplant. Plants in this family contain various natural compounds, known as glycoalkaloids , whose presence has pesticidal action against insects, fungi, and bacteria.

Specifically in the tomato, solanine and tomatine are found . Both compounds are considered harmful or toxic to dogs and other animals, especially when ingested in large amountsone 2 .

But a very important fact to consider is that, although these substances can be found throughout the plant, only the leaves, stems and green tomatoes have significantly high concentrations.

According to the researchers, the tomato or ripe tomato does not contain dangerous amounts of solanine and tomatine , which is why its moderate consumption is safe for dogs3 .

So, can a dog eat raw tomato without risk of poisoning? Yes. Dogs can safely eat tomato , as long as it is well ripe (red) and is administered in small portions .

What parts of the tomato should not eat a dog?

Dogs should NEVER eat:

  • Green tomato or not fully ripe (pintón)
  • Stems , leaves , flowers , or other green parts of the plant

These parts contain higher concentrations of toxic substances, and can reach up to 5% tomatine.

Toxic symptoms: what happens if a dog eats a tomato?

In case the dog has eaten green tomato , or chewed the green parts of the plant, it is necessary to observe it to detect possible signs of tomatine / solanine intoxication.

The most common symptoms and side effects in dogs are:

  • Gastrointestinal upset ( vomiting , diarrhea )
  • loss of coordination
  • Dilated pupils
  • Muscular weakness
  • tremors
  • seizures
  • Slowing of the heart rate
  • Lethargy
  • excessive drooling
  • behavior changes

It should be noted that most of these symptoms are rare, as a dog would have to eat large amounts of tomato to experience them. Even so, it is warned that in case of ingestion accompanied by any of the above symptoms, it is necessary to go to the veterinarian immediately.

In general, the prognosis for dogs poisoned by eating tomato is good .

Treatment: Is Canine Tomato Poisoning Treatable?

Yes. A dog that experiences symptoms of toxicity after ingesting green tomatoes (or parts of the plant) should receive medical attention as soon as possible.

One of the most common treatments is fluid therapy . This is especially recommended if the pet is vomiting and has diarrhea . During fluid therapy, the vet pumps electrolytes and fluids into the dog’s body to treat dehydration as well as flush out toxins responsible for poisoning.

Another form of treatment is gastric lavage , which helps remove toxins from your system when vomiting cannot be induced .

In very severe cases where the dog is having difficulty breathing, the vet can create an emergency airway to prevent suffocation.

Depending on the amount of tomato eaten, the prognosis varies from fair to excellent. There is no specific antidote available and treatment is primarily focused on managing symptoms and providing support.

Warnings and useful tips for owners

The following precautions can help prevent dog poisoning from inappropriate tomato consumption :

  1. Prepare the tomatoes properly . Be sure to remove any green parts of the plant that may remain on the ripe tomato you give your dog, as well as any other tomatoes within reach in the home.
  2. Control portion size . Limit the amount of tomato eaten. Although the natural ripe tomato can be an excellent vegetable for dogs , its excessive consumption can have negative effects.
  3. Keep tomato plants fenced at home . If you are someone who prefers to grow their own organic tomato plants in the yard or garden, be sure to put up a dog-proof fence to prevent the pet from eating green tomatoes or chewing on the stems and leaves. If you have the tomato plant in a pot inside the house, it must be placed completely out of reach.

What is the best way to give a dog tomato?

The best tomato for a dog is one that is fresh , ripe , completely red and juicy . Regardless of whether it is organic or not, you should rinse it with plenty of water to remove microorganisms and possible traces of pesticides.

How much tomato can dogs eat?

There is no standard serving size of tomato that is considered ideal for dogs . Every dog ​​is different and tomato tolerance can vary. Even with the ripe tomato, it is important not to overdo it.

As a general rule, the smaller the dog, the smaller the size of the portion eaten. It is recommended to give them only a few slices per meal or snack , without exceeding the number of 1-2 medium tomatoes per week.

Although in lower concentration, the ripe tomato still has solanines, and in addition, it is still a source of carbohydrates.

Quick Answers to Frequently Asked Questions

What to do if a dog eats a green tomato?

In the event that a dog has eaten green tomato , but only a small amount, it is recommended to observe it for the next few hours to detect if it develops symptoms of tomatine poisoning . The same should be done in case you have chewed a small part of the plant.

When ingestion is minimal, many dogs show no signs of poisoning. Other dogs, on the other hand, can be especially sensitive and experience an adverse reaction.

Now, if the dog ate a significant amount (1 or more green tomatoes), then it is best to quickly consult the vet. Depending on the state of the pet, he may recommend making him vomit and going to the clinic as soon as possible.

Activated charcoal administration is another good tool to neutralize toxins in the stomach.

A dog poisoned by eating tomato requires urgent medical attention if it is already showing symptoms.

Can dogs eat cooked tomato?

Dogs can eat ripe tomato raw or cooked. But in the case of cooked tomato, it is important that it is in its most natural form possible .

Commonly, the tomato that we use in stews, sauces and other recipes is a processed version (fried tomato, puree, paste, etc.), which may contain preservatives, salt, sugar, seasonings. If so, it is not recommended.

In addition, some preparations are not suitable for dogs , even if they contain the natural fresh tomato. For example, a food that includes tomato and onion, or tomato and garlic, is not considered safe for the pet. Dogs should not eat vegetables from the allium family.

Can dogs eat tomato puree, sauces and ketchup?

Although they are not as toxic as the green tomato , common tomato sauces and ketchups are also often contraindicated in dogs . The vast majority of tomato products contain other ingredients and additives that are harmful to these animals.

They are usually high in sodium, sugar, hydrogenated oils, preservatives, artificial flavors, and spices like garlic and onion. This is even more noticeable in tomato pasta sauces.

A special caveat for ketchup is that some brands use xylitol as a substitute for sugar. Xylitol consumption is highly prohibited in dogs ; this can be fatal.

Be sure to read the ingredient list carefully before allowing your dog to taste any commercial tomato puree or sauce , as well as foods that contain them.

Can my dog ​​have tomato soup?

A dog could safely drink tomato soup if it has been designed and prepared for consumption by dogs. Commercial soups and homemade spicy soups are not good choices for your pet, as they contain potentially toxic ingredients (sodium, spices, chemicals).

Can dogs eat canned tomato?

Canned tomatoes may be dog-friendly, but it’s important to make sure they contain only red ripe tomatoes , with no additives or preservatives . Considering that many of these products include ingredients such as sodium, sugar, preservatives, and flavor stabilizers, it’s best to stick to fresh tomatoes and avoid canning .

Can I give my dog ​​macaroni and tomato?

A dog should not eat macaroni, or other pasta, with tomato if the sauce used is canned. The high sodium content and the presence of toxic spices for dogs, such as garlic and onion, can put them at risk of dehydration and poisoning .

The same thing happens if the macaroni has a homemade tomato sauce with too much salt and too many spices.

In order for a dog to safely eat tomato macaroni , the paste should only contain natural ripe tomato.

Note . Avoid giving your dog large portions of tomato macaroni. A healthy canine diet should never be high in carbohydrates.

Can dogs eat cherry tomatoes?

Is it safe for a dog to eat tomato peel?

Ripe tomato peel is not considered especially dangerous to dogs . Even so, many recommend removing the skin or washing it with plenty of water to remove possible traces of pesticides, herbicides and toxins. This is even more important when the tomato is not organically grown.

How much tomato could kill a dog?

Only the ingestion of large amounts of tomato , and therefore of tomatine, could cause the death of the dog. According to studies on the toxicity of glycoalkaloids in green tomatoes, a 60-pound (27-kg) dog would need to eat 2.7 grams of tomatine to have a chance of dying. That means he would have to eat approximately 472 tomatoes.

Maintaining the same level of toxicity for other sizes, a 30-pound dog would need to eat 236 tomatoes, and a 10-pound dog would need 78 tomatoes.

As you can see, solanine and tomatine are toxic compounds for dogs, but the risk of death by poisoning in this case is very low .

Can puppies and older dogs eat tomato?

In general, it is not a good idea to give a puppy a tomato ; it is best to wait. It is noted that the stomach of puppies is much more sensitive than that of an adult dog, hence there is a greater risk of poisoning and digestive problems.

In the case of older dogs, tomatoes can be part of their regular diet, as long as they are ripe and the portion is small. Vegetables, including tomatoes, can contribute to better nutrition and the prevention of degenerative diseases.

Can dogs be allergic to tomato?
