If you are a tomato lover, then trust me, you are not alone. However, have you wondered – Can Dogs Eat Tomato Sauce? If yes, then I will answer this question for you today. Not just tomato but prominent tomato by-products such as tomato sauce are loved by far too many Americans.

While your dog may love a bite of tomato now and again, experts agree that you should keep your furry canine friend out of your garden, and here’s why.

Can Dogs Eat Tomato Sauce?

A less alarming fact: Where there’s food, there’s your dog, and you may be wondering if you may share the delectableness with your four-legged companion.

Tomatoes are members of the nightshade vegetable family. This plant, which includes eggplant, peppers, and potatoes, has potentially toxic chemicals yet has edible sections.

That is, while tomato fruits are good for your dog and may be provided as a treat on occasion, the remainder of the tomato plant might be harmful.

The hazardous ingredient present in tomato plants that are connected to solanine, the deadly compound found in other nightshades, is alpha-tomatine. When taken in excessive amounts, it can be fatal to your dog.

Tomatine is abundant in the plant’s green sections, particularly the short stems and blossoms.

Many vets believe that while your dog would need to consume a substantial number of tomato plants (including the green parts) for the toxin to create dangers like sleepiness, slowed heart rate, and dilated pupils.

Tomato sauce, like ketchup, is not hazardous, but it may include substances that are harmful to dogs. Garlic, onion, salt, pepper, oregano, basil, red pepper, and sugar are frequently used to flavor marinara sauce, so read the label carefully.

Garlic and onions are the most dangerous since they are poisonous to dogs. Especially for tiny dogs or when consumed in large quantities.

Thiosulphate is a component found in onions and garlic and can harm a dog’s red blood cells, resulting in anemia or death. If swallowed, the following symptoms may occur vomiting, diarrhea, stomach discomfort, and weakness.

Other symptoms, such as tiredness, pale gums, and weight loss, may take a few days to appear. If these symptoms arise, take your dog to the vet as soon as possible.

Although they aren’t the best, sugar, salt, and crushed red pepper is less harmful components. Dogs are sodium-sensitive, and too much might result in sodium poisoning.

Too much sugar is bad for everyone — two or four legs – and can lead to obesity and heart disease. As with ketchup, the artificial sweetener xylitol, which can be poisonous to dogs, is worse.

Even trace quantities can be fatal. The crushed red pepper should be avoided since its spiciness might upset your dog’s tummy.

Toxicity levels vary according to your dog’s size and the amount ingested. Large dogs are unlikely to experience any major adverse effects from consuming a small amount of tomato sauce.

Smaller dogs ((< 10 pounds) may become ill. It is advised to call your doctor if your dog has ingested a big amount for its size. They will notify you of any symptoms to be on the lookout for.

Another advantage of ingesting lycopene is that it lowers the chance of getting some malignancies, such as lung and prostate cancer.

As per research, eating a diet rich in carotenoids (including lycopene) reduces the risk of lung and prostate cancer by 32-50 percent.

While tomatoes are not toxic to dogs, giving your dog tomato sauce is not advisable.

Tomatoes are members of the Solanaceae family of very poisonous plants. The good part is that these poisons are only found in specific sections of the plant and are only active during specific phases of the plant’s development.

In the case of the tomato, the toxin is known as “alpha-tomatine,” and it is found in high concentrations exclusively in unripe tomatoes.

Ripe tomatoes have very little alkaloids, and your dog would have to consume a lot of tomatoes to acquire even the mildest kind of poisoning.

Tomato sauces, particularly readymade sauces, are loaded with additives other than tomatoes. Some of the components discovered include garlic and onion, neither of which is beneficial to your dog. This is particularly true with garlic.

Garlic includes “thiosulphate,” which destroys red blood cells and causes anemia in dogs. In the worst-case situation, it might potentially result in death.

Thiosulphate poisoning symptoms include vomiting, weakness, and diarrhea. Tomato sauce contains salt, sugars, and pepper, which are all safe for dogs if consumed in moderation.

The good news is that tomatine is concentrated in the plant’s green sections, particularly the blossoms and tiny stalks.

The tiny quantity of tomatine found in ripe tomatoes is deemed safe for dogs. Green tomatoes have more tomatine, although the difference is likely insignificant.

Pet parents should be aware that the tomato plant’s blooms, leaves, and stems contain tomatine, which can be toxic to dogs. On the other hand, dogs are unlikely to consume enough of the herb to cause issues.

Large grazing animals, such as cattle, are most vulnerable to tomato plant poisoning. Having said that, it’s still a good idea to keep a watch on your dog anytime they have access to your garden.

The most common symptom of tomatine poisoning is gastrointestinal distress, such as diarrhea or vomiting.

However, if dogs consume large amounts of the tomato plant, they may also exhibit symptoms such as depression, muscle weakness, hypersalivation, dilated pupils, or an abnormal heart rate—in which case you should seek immediate treatment from your pet’s veterinarian.

Tomatoes, like humans, can worsen some gastrointestinal conditions, such as acid reflux. Therefore it’s always a good idea to see your veterinarian before feeding tomatoes to your dog.

Tomatoes are also a frequent allergy in people, and while it’s unlikely, your dog may have a similar response.

Also, the sauce they come in isn’t harmful in any manner, but it’s also not very nutritious. To put it simply, pilchards with tomato sauce are only okay to feed to dogs as an occasional snack.


The pilchards are good for your dog, but you should check the label carefully since the tomato sauce may include substances that are harmful to dogs. There is only around 65 percent fish and 35 percent tomato sauce in a typical can.

There’s nothing wrong with tomatoes; they’re actually beneficial to your dog. Dogs are only poisoned by the green sections of the tomato plant.

However, according to the label, a standard can have 1.55 g of salt. According to the manufacturer, this amounts to around 26% of the typical person’s recommended daily intake (RDA).

That’s a lot for a dog, especially when it comes to little breeds. Excessive salt consumption can result in vomiting, diarrhea, tremors, fever, and seizures.

The quantity of salt in a can of pilchards will not cause salt poisoning, which may be fatal, but if you give salty fish to your dog every day, he may develop health problems.

Because tomato sauce contains too much salt, it is not good for a dog. Pilchards in brine should be avoided since the salt level is considerably higher.

Over time, eating too much sugar can lead to obesity (a risk factor for the development of diabetes) and dental problems.
