Can Dogs Eat Tomato Soup?

Many people are fond of the smell of tomato soup, especially in the winter when the weather is cold. Since dogs also enjoy human food, it is not surprising that they may beg for it. Is it okay for dogs to try tomato soup? It really all depends on what is in it, as some people may use ingredients that are potentially toxic to dogs.

Is Tomato Safe For Dogs?

Some components of tomatoes are safe for pets, others are not. Some dogs in nature have an allergy to tomatoes. That’s why it’s crucial to know which components are safe for your dog to eat.

Safe components of tomato

Dogs should never eat the stem, roots, and leaves of ripe tomatoes, nor should they eat unripe tomatoes. These contain up to five percent of a substance called tomatine, which has been deemed toxic to dogs. The amount of tomatine in the stem, roots, and leaves would be enough to poison your dog. Some may wonder if ripe tomatoes contain this substance, especially since it comes from a poison that exists in most plants in the nightshade family. While tomatine is found in ripe tomatoes, there are very small amounts, making them safe for dogs to eat. However, feeding puppies ripe tomatoes is not advised as their immune systems are still developing. If you are enjoying this article, check out our article on the best dog food for anal gland.

Precautions to Growing Tomatoes

Many people grow their own tomatoes because it is relatively easy in many climates; this is a good way to know where your tomatoes come from and what fertilizers are used. However, pet owners should exercise caution with their gardens and their pets.  The best option would be to build a fence around your plants to avoid potential issues.

Allergy to tomato soup

While a dog may not be allergic to tomato soup itself, it could be allergic to an ingredient in it, but it is rare. Regrettably, the only way to discover this is by trial and error--feeding your companion some soup and waiting for at least a half an hour to see if there is a reaction.

Is tomato sauce safe?

Your furry friend can eat several foods. Yet, not everything your dog begs to eat is healthy for him. Whereas tomato is healthy for dogs on its own, tomato sauce isn’t safe for him. Tomato sauce contains onions and garlic. In spite of the fact that these two ingredients are healthy to humans, they can be toxic to dogs, especially since their digestive system is different from that of a human.

As a dog owner, you might not always be monitoring what your furry friend does, eats, or drinks. If you notice any poisoning symptoms in your dog after discovering he’s accidentally eaten tomato sauce, rush him to his vet, especially if he’s small.

How much tomato is safe for dogs?

While there’s no direct way to know how many tomatoes your dog can eat, one clever way is to feed small dogs small amounts; and offer bigger dogs larger amounts.

Moreover, if it’s the first time for your dog to eat ripe tomatoes, offer him very few slices till you know his body gets used to it.

One to two pieces are okay per week. This amount prevents your dog from being exposed to tomatine and its consequences. If you are enjoying this article, check out our article on the best dog food for westies.


In a nutshell, if your dog’s vet gives you the OK to feed your dog tomatoes or tomato soup, consider removing the parts considered toxic to dogs like the stem, the roots, and the leaves. Don’t forget to stop feeding him this soup whenever you notice any unusual symptoms. If you are enjoying this article, check out our article on the best dry dog food for maltipoo.
