Can Dogs Eat Tomato Sauce?

Dogs are not harmed by tomato sauce alone. Premade pasta sauces could be harmful to dogs.

It’s not to say you should take your dog to the vet each time they eat some marinara off the floor. Dogs can’t look after themselves, so their owners must care for them.

You’ve found the right place to learn how to make tomato sauce for your dog and what to do if your dog gets sick of tomato sauce.

Dogs Can Eat Most Tomatoes?

Tomatoes belong to the nightshade family. This group includes plants that contain both nutritious vegetables and dangerous poisons. Nightshades contain solanine, and tomatoes have tomatine.

Tomatine can cause severe health problems in dogs and humans. Red tomatoes are free of it. The most toxic tomatine is found in tomato plants’ stems and leaves, as well as unripened green tomatoes.

You can keep your dog out of your tomato garden by erecting a fence.

Ripe tomatoes are safe for dogs and can help them obtain nutrients. Even though dogs don’t require vegetables like humans, they can still benefit from veggies to live longer and happier lives.

Can Dogs Eat Tomato Sauces?

Pasta sauces and tomato sauces are made with more than just tomatoes. The most common suspects are onion, garlic, salt, and others.

Not all ingredients in a tomato sauce are harmful. Salty foods can make your dog feel thirsty. Sugar can only be harmful if consumed in large amounts for a long time, which can increase their chances of developing diabetes and obesity.

The real problem is garlic and onions, found in nearly every premade tomato sauce and many canned “ingredients” flavorings.

In large quantities, garlic and onions can cause severe poisoning in dogs. They damage your dog’s red blood cells and can cause weakness, anemia, or even death.

Side Effects Of Dogs Eating Tomatoes


A quick visit to the vet would be a good idea if your dog ate a tomato plant.

Even though it is rare, tomatine poisoning can prove fatal.

Be on the lookout for these symptoms:

  • Drooling
  • Diarrhea
  • Vomiting
  • A decreased heart rate
  • Tremors and seizures
  • Loss of coordination/weakness
  • Unregular heartbeat
  • Lethargy
  • Dilated pupils
  • Paralysis

These symptoms are not common, but we recommend keeping an eye on your dog. Also, inform your vet if your dog does any unusual activity.

What To Do If Your Dog Eats Pasta Sauce?

First, be kind to yourself. If your dog eats something unwholesome, you can’t stay awake every minute. Every pet owner will experience this at some point.

Second, don’t panic. You won’t see your dog suffer anything more than an upset stomach unless they are tiny or have eaten a large amount of sauce. Do not be afraid to act with diligence.

Tell your vet what your dog ate and how much. You should be able to refer to the ingredients on any sauce jars or canned foods. If your dog has any symptoms, let them know.

Your vet will advise you to bring your dog to the pet hospital or leave them at home while you monitor them. If the former, you can keep your dog close to you for several hours and call again if they start showing any of the symptoms mentioned above.

Last Thoughts

Even if you make homemade dog food using dog-safe tomato sauce, remember that your dog should not eat more than 10% of their daily food intake. High-quality, organic dog food is better for dogs than any other food.
