Can Dogs Eat Ketchup?

Before we answer the question, it is pertinent to note that ketchup, albeit most popularly can be found as tomato ketchup, can be made of other items like mushrooms, egg whites, etc.

But, since most people refer to tomato ketchup as ketchup, we, too, will be sticking to whether your dog can eat tomato ketchup!

Now, getting right to it, yes, dogs can eat ketchup. But not as a regular inclusion in its diet or even as a regular treat.

The reason – commercially available ketchup is manufactured using various flavoring ingredients like garlic, onion, spices, etc., along with preservatives and other chemicals.

An example of a chemical that most manufacturers use to manufacture ketchup is xantham gum. This stabilizing agent has been proven to be toxic for dogs in large quantities.

While ripe tomatoes themselves are not harmful to dogs, these other ingredients can negatively affect your pooch’s health and digestive system. Therefore, as far as possible, you must simply avoid feeding ketchup to your dogs or letting them eat it.

Ketchup Nutritional Facts

Here are some nutritional facts about ketchup –


Ketchup is fairly rich in carbohydrates. Per the USDA, of the 15 grams in a single serving of ketchup, over four calories are attributed to carbohydrates. However, the glycemic load of these carbohydrates is quite less.

Vitamins and minerals in ketchup

Ketchup is not an excellent source of micronutrients because it is ingested by both you and certainly your pet dog in such small amounts.

Tomatoes, the major component, are abundant in vitamin C and vitamin A, as well as vitamin K, potassium, and manganese (depending on the amount consumed).

However, your pup is highly unlikely to consume enough ketchup to obtain significant amounts of any of these nutrients.

Fats and protein

Ketchup, and even tomatoes, aren’t the best source of fats or proteins. Therefore, as far as meeting your pet dog’s dietary requirements of fat and protein, ketchup will prove to be entirely unhelpful as an addition to its diet.

The fact is that ketchup by itself is not a particularly nutritious food for your pet dog. In fact, it adds little to no value to your pet dog’s diet!

Health Benefits Of ketchup For Dogs

Ketchup, as we have stated, has no nutritional value. Because most brands and types of ketchup contain high quantities of sugar and salt, the risk to reward ratio in terms of your pet dog’s health is extremely high!

However, the main ingredient used to create ketchup, i.e., tomatoes, especially the ripe ones, offer immense benefits to dogs and humans alike. Your veterinarian would likely agree to choose to feed your pet dog tomato purees every other day rather than feeding it ketchup!

Ketchup in bottle

Tomatoes, unlike ketchup, are high in nutrients. Tomato pomace, which is the pulp, skin, and crushed seeds of tomatoes, is found in some dog foods. Tomato pomace is high in fiber, which helps dogs with constipation and promotes good digestion and bowel movements.

Tomatoes are extremely rich in vitamins A and C, making them an excellent immune booster. Tomatoes also contain potassium, which helps to keep the blood pressure of your pet dog in check.

Tomatoes include lycopene, which enhances bone health and may lower the incidence of stroke.

Risks of Eating Tomato Ketchup in Dogs

The risks of eating tomato ketchup far outweigh any possible benefits that your dog may glean from it. Apart from the lack of any nutritional advantages, ketchup can also be harmful to your pet dog.

Here are some of the commonly observed adverse effects that eating ketchup could have on your pet dog.

Unhealthy weight gain in your pet dog

The bulk of calories in ketchup come from carbohydrates. In addition, commercially manufactured ketchup is created by adding sugar and artificial sweeteners to it.

Therefore, your dog could put on unhealthy amounts of weight as a result of the sugar content of ketchup in the long run and suffer from the short-term effects of consuming sugar in large quantities, like diarrhea and nausea.

In the long-term, your pet dog could become obese and suffer from chronic health problems such as blood sugar issues, high blood pressure, and so on.

Digestive distress on eating large amounts of ketchup

Most typically, dogs begin to experience severe diarrhea upon eating large amounts of ketchup. This could be because of the high amounts of sugar in most commercially available ketchup or due to the other spices and additives present in it.

You may even have to consult your vet if your dog’s digestive system doesn’t ease up or persists for a long time.

Chronic blood sugar issues

If your dog eats sugary foods, like most commercially available ketchup, on a daily basis, diabetes is a definite possibility. When a dog consumes more sugar than its digestive system can process efficiently, it develops diabetes.

Because ketchup includes a lot of sugar, diabetes is something to keep in mind if you plan on giving your dog ketchup on a regular basis.

Presence of ingredients such as garlic and xylitol

Ingredients like garlic and xylitol are known to be extremely harmful to dogs. The reason is that garlic contains a compound that often leads to a condition is known as hemolytic anemia in dogs and causes poisoning.
