Why
Ripe tomato flesh is generally non-toxic, but ketchup is a processed condiment. A representative USDA entry contains about 907 milligrams of sodium and 21.3 grams of total sugars per 100 grams. Many recipes include onion powder; garlic is not universal. Sugar-free does not mean xylitol, so check the label and call immediately if a dog product lists xylitol or birch sugar.
Risks to watch for
- Onion or garlic powder in a recipe can damage red blood cells
- High sugar and sodium contribute to weight gain and excessive thirst
- Xylitol or birch sugar on the label is life threatening to dogs
- Vinegar and spice commonly cause vomiting or diarrhea
What to do if your dog ate ketchup
