Where does ketchup come from?

Ketchup is a tangy, sweet sauce made from tomatoes which originated in ancient China. Ubiquitous on restaurant tabletops across the United States, ketchup is extremely popular: so much so that it can be found in 97% of American kitchens. The red stuff is used as a tasty condiment on top of hamburgers, hot dogs, sandwiches, and French fries.


Can dogs eat ketchup?

No, dogs cannot eat ketchup. Although certain parts of fresh tomatoes are generally harmless to dogs (except for the green portions which contain the toxin alkaloid tomatine), ketchup is a completely different jar of sauce. Ketchup contains additional flavorings, such as onion powder and garlic powder, which can be harmful to your pet if consumed in large amounts.

What are the concerns with feeding ketchup to dogs?

The primary concern is that the seasonings in ketchup are not dog-friendly, and can be potentially dangerous to your furry friend. Additionally, the high sodium content in ketchup is not good for your canine. Keep these things in mind when consuming ketchup around your doggo.



Onion powder is one ingredient in ketchup that is toxic to your pet. According to the AKC, all parts of the onion are toxic to dogs and should not be consumed in any form, be it fried, raw, or powdered. Onion powder can be extremely potent, so it's very important that your dog not consume it, or items that have onion powder in it.

According to the AKC, these are the symptoms of onion toxicity in dogs:

  • Lethargy
  • Weakness
  • Decreased appetite
  • Pale gums
  • Fainting
  • Reddish urine
  • Panting
  • Vomiting


If your dog exhibits these symptoms, or any unusual behaviors contact your veterinarian right away.


Ketchup can often times contain garlic powder as well, which is not good for your furry friend. According to the AKC, some dogs are more sensitive to garlic than others: if your dog accidentally eats a little garlic, he will probably be ok, but every dog is different. Ultimately, ingesting large amounts of garlic and garlic powder can be bad news for dogs and lead to poisoning.


If your dog ingests garlic or food with garlic in it, be sure to monitor him for symptoms and contact your veterinarian if need be.

High sodium content


Ketchup is high in salt, and high sodium foods can be dangerous for your pet to consume. While salt in moderation is not bad for your pet, according to Pet Poison Hotline, salt is potentially poisonous to dogs if eaten in large quantities and puts your dog at risk for seizures, coma, or even death.

Here are the common signs of salt poisoning to watch out for in dogs:

  • Vomiting
  • Diarrhea
  • Decreased appetite
  • Lethargy
  • Incoordination
  • Excessive thirst or urination
  • Tremors
  • Seizures
  • Coma


If you believe your dog ie experiencing signs of salt poisoning, call your veterinarian immediately.
