Did you know?
Ketchup originated in China as a fermented fish sauce called ke-tsiap that bore no resemblance to modern ketchup. This sauce reached Britain via the spice trade and was adapted using mushrooms walnuts and anchovies before tomatoes were added in the early 1800s. The word catsup — still used in some regions — is a direct transliteration of the original Chinese term. Heinz introduced its tomato ketchup in 1876 with a sweetened tomato base. The garlic and onion powder that makes ketchup toxic to dogs is not part of the original formula — it was added as flavoring in commercial production.

What You Need to Know
Ketchup universally contains garlic and onion powder — the seasoning that makes it toxic to dogs. The typical tomato base is not the problem; the Allium seasonings are. Even small amounts of ketchup added to dog food over time cause cumulative Allium toxicity. Never use ketchup as a food topper or flavoring for dogs.
