Frequently Asked Questions

Why is ketchup bad for dogs?

Standard ketchup contains high sodium, high sugar, and often onion powder. Some specialty ketchups contain xylitol (a sweetener that causes life-threatening low blood sugar in dogs).

My dog licked some ketchup — is it an emergency?

Check the label first for xylitol. If present, call your vet immediately. If it’s regular ketchup without xylitol, a small lick is unlikely to cause harm. Monitor for GI upset.

Does ketchup contain onion?

Many ketchup brands include onion powder in their spice blend. This makes it inappropriate for dogs, as onion in any form (fresh, dried, powder) is toxic and causes damage to red blood cells.

Are there dog-safe ketchup alternatives?

Pureed plain tomatoes (no seasoning, no onion) can be used as a small food topper that provides similar lycopene benefits. Plain unsalted tomato sauce in very small amounts is the closest safe alternative.
