Can dogs eat Ketchup?

Yes, dogs can eat Ketchup, but it is not recommended. While some parts of fresh tomatoes are naturally safe for dogs (leaving out the green parts which have the toxin alkaloid tomatine), Ketchup is a very different matter. 

Most brands of Ketchup add various chemical food preservatives, artificial flavorings such as onion powder and garlic powder, and artificial colorings that aren’t suitable for your dog’s well-being – some could even be lethal.

Different flavored Ketchup, like hot and spicy, sriracha, and jalapeno, can contain more harmful additives. Therefore, it’s best to refrain from giving your dog food with Ketchup. 

Tomatoes themselves are harmless in dogs, except for the stems, leaves, and flowers. They contain high concentrations of tomatine, which are toxic to dogs. Mild digestive upset is the most likely result when dogs consume tomato greenery.

What ketchup ingredients are bad for dogs

Garlic and Onion

Ketchup contains garlic and onion, which are unhealthy for dogs. These spices are members of the Allium family, which has Sulfoxide and n-propyl disulfide.

These chemicals produce a fog that damages red blood cells in large amounts. This damage causes anemia and red or brown urine. As such, dogs shouldn’t eat Ketchup.


Sodium is likewise included in store-bought Ketchup and high percentages, making it hazardous for dogs. Sodium content from the added salt can leave your dog dehydrated, but this also isn’t a grave matter if they’ve only had a few nibbles.


Another ingredient you have to be wary of is giving your dog too much sugar. This will occur when you feed your pet ketchup frequently. And this will make your dog grow fat and become overweight, leading to some severe health conditions, such as joint problems, diabetes, and heart diseases.


While it appears as though sugar is among the major culprits in ketchup consumption in dogs, still, never consider feeding your dog the sugar-free version.

Sugar-free products often contain xylitol, a sugar substitute, another substance that is very toxic to your dog. When dogs consume xylitol, it triggers a significant insulin release, causing hypoglycemia (low blood sugar), seizures, liver failure, or even death in dogs.

Xanthan gum is a food additive that helps increase the thickness of Ketchup. Although this stabilizer is safe for humans, it can be lethal to dogs. Xanthan gum is ‘safe’ in normal portions, but it can cause an upset stomach, such as diarrhea and bloat in huge portions.
