Can Dogs Eat Ketchup? Quick Answer!

Ketchup is a popular sweet sauce. I’m not the biggest fan of ketchup myself, however, a lot of people eat ketchup almost every day. A lot of people also feed food leftovers to their dogs. That’s one way how your dog could end up eating ketchup. However, can dogs eat ketchup?

The short answer: Ketchup is unsafe for dogs to eat because some of the ingredients of ketchup are dangerous for dogs.

Can Dogs Eat Ketchup? Ketchup Can Be Dangerous for Dogs

It’s not okay to let your dog eat ketchup because some of the ingredients of ketchup are dangerous for dogs. If we take a look at the ingredient list of Heinz tomato ketchup, then one of the things we find is onion powder. Onion powder is used in ketchups to add flavor. It’s not only used in Heinz ketchups, but in most other ketchups as well. Sadly, this is the ingredient that makes ketchups unsafe for dogs. Because for dogs, as you may know, onions are toxic, and so is onion powder[1].

Another reason why you shouldn’t let your dog have ketchup is that most ketchups contain a lot of sodium. One tablespoon of ketchup contains about 154 milligrams of sodium. That’s 54 milligrams more than the recommended daily amount for medium-sized dogs[2].

It’s never a good idea to feed your dog such sodium rich food. While a small amount of sodium is necessary for your dog to be healthy, a large amount is actually toxic to dogs[3]. Going a little over the recommended daily sodium intake level is not life-threatening to your dog, but it will cause excess thirst and urination. Going more than a little over the recommended daily sodium intake level, however, can cause kidney damage and is life-threatening for dogs.

What If My Dog Already Ate Ketchup?

can-dogs-eat-ketchupIf your dog already ate some ketchup, then reading this article might have got you worried about your dog’s health. If your dog only had a little bit of ketchup, then there’s no need to worry.

Thankfully, ketchup doesn’t contain a lot of onion powder. And, as I already mentioned above, going a little over the daily recommended sodium intake level is not life-threatening for your dog.

However, if your dog had more than a little bit of ketchup, then it would be best to keep a close eye on her. If your dog starts to vomit or is unusually inactive, then contact a veterinarian.

Conclusion on Can Dogs Eat Ketchup

In conclusion, I would like to say that it’s definitely for the best to keep ketchup out of your dog’s diet. Your dog might have not got sick that one time you fed her leftover French fries with ketchup, but that doesn’t mean that ketchup is okay for your dog to eat. Ketchup contains onion powder, which is toxic to dogs, and an unhealthy amount of sodium. There’s plenty of other things you can feed your dog without having to worry about setting her health at risk.
