Are cooked tomatoes bad for dogs? Health risks

Cooked tomatoes are healthy for dogs but pose a few risks, especially in large amounts.


Nightshade plants are an allergen in the dog world, and some pups may develop allergic reactions on the first interaction with tomatoes.

Mild reactions manifest as vomiting, bloating, excessive itching and paw licking, hot spots, and skin problems.

Some canines may experience extreme sensitivity to cooked tomatoes and develop severe reactions after ingesting them.

Stop feeding cooked tomatoes to your pet and contact your vet immediately to avoid further complications.

Sodium poisoning

The level of sodium is high in processed or stewed tomatoes.

This increases the chances of your dog developing diabetes and metabolic disorders if consumed often.

Store-bought cooked tomatoes, popular among households, contain loads of sodium-based preservatives like nitrates and nitrites.

Symptoms of high sodium intake in dogs:

  • Vomiting
  • Diarrhea
  • Lethargy
  • Abnormal fluid accumulation
  • Kidney damage
  • Seizures or coma

How do I safely feed my dog cooked tomatoes?

Knowing the benefits of tomatoes for your dog is one part of the puzzle.

The how-to feed them matters in maximizing the nutritional elements and reducing health risks. 

Proper preparation: Remove all the green foliage parts of the tomatoes and clean them gently before feeding your dog. Make bite-size cuts and cook without oil or spices.

Moderation: Although tomatoes are safe for canines and present in most commercial dog food, serve them sparingly. Otherwise, too much may cause gastrointestinal upset.

Plain puree: Feed your pup plain tomato sauce. Instead of store-bought sauce, blend a few at home and give your furry pal. Make sure commercial sauces are free from additives.

What should I do when my dog overeats cooked tomatoes?

In case your dog overeats cooked tomatoes, you first want to find out the ingredients in the cooked tomatoes and the amount ingested.

Plain or mildly seasoned (dog-safe spices) cooked tomatoes will result in mild gastrointestinal issues that will subdue shortly; no need to panic.

Watch out for signs like drooling, low appetite, and behavioral change.

Monitor them closely, and offer plenty of water.

On the flip side, if your dog ingests large amounts of heavily seasoned cooked tomatoes, there is a likelihood of developing sodium poisoning.

It manifests as gastrointestinal upset, lethargy, and seizures; contact your vet immediately if you see these signs.

Can dogs eat unripe tomatoes?

Unripe tomatoes contain traces of toxins (solanine and tomatine) which cause tomato toxicity, otherwise known as tomatine poisoning.

Solanine is concentrated in the green parts of tomatoes—ingesting it in large amounts causes stomach irritation and gastrointestinal upsets.

Nonetheless, it’s unlikely for canines to ingest many unripe tomatoes enough to cause tomatine toxicity.

However, for small breeds like Chihuahua, even a tiny amount could lead to tomatine poisoning.

The severity of the symptoms depends on the number of unripe tomatoes ingested, dog size, and preexisting medical conditions.

Symptoms include;

  • Poor appetite
  • Gastrointestinal upset (vomiting, diarrhea)
  • Drowsiness
  • Muscle weakness
  • Behavioral change
  • Lethargy
  • Seizures

Can dogs safely eat tomato sauce?

A tomato-only puree is safe for your dog to consume.
However, most commercial ketchup and sauces contain additives like chives, garlic, and onions, which can harm your dog’s health.
Although plain sauces are safe for dogs, most lack adequate nutritional value.
Carefully read the label for ingredients since most ketchup contains sugars harmful to dogs.
Some plain sauces are loaded with artificial sweeteners like xylitol which is a lethal component to dogs even when ingested in small amounts.
Xylitol poisoning is fatal if not treated immediately.
Contact your vet if you notice lethargy, excessive drooling, and seizures.

Let’s wrap it up

Plain and unseasoned cooked tomatoes are an excellent addition to your dog’s diet.

They increase their nutritional intake of minerals, vitamins, and antioxidants essential for proper functioning.

Unfortunately, the nutrient-dense profile is accompanied by some toxicity (tomatine poisoning) dangerous to canines but in unripe form.

Now that you have the details on safely feeding your dog cooked tomatoes have fun sharing this nutritious veggie with your furry friend.
