My dog ate sugar-free gum.
Is it xylitol?

Xylitol drops a dog's blood sugar fast, signs can start within 30 minutes. Check the package: if xylitol is in the ingredients, use the calculator. If you can't tell, treat it as yes.

1 · Dog's weight
2 · How many pieces of gum / mints?
Xylitol per piece varies wildly by brand: 0.3-1 g or more per piece. This calculator assumes 0.5 g per piece as a middle estimate, if the package lists xylitol per serving, use that (grams eaten ÷ 0.5 = "pieces" to enter). Ate xylitol peanut butter or baked goods? Skip the math, call.

Why xylitol is different

In dogs, xylitol triggers a massive insulin release. Published thresholds: hypoglycemia from about 0.1 g per kg body weight, and liver injury from about 0.5 g/kg. A single stick of gum can be enough for a small dog. Cats appear far less sensitive but data is limited.

The catch: labels hide the amount

Most gum brands don't publish exact xylitol content, and "sugar alcohols" on the label may be mostly xylitol. That's why every poison-control service says: when in doubt, call. It's also in some peanut butters, toothpastes, melatonin gummies, and baked goods.

What NOT to do

Do not wait for symptoms, early treatment is simple (sugar support) and late treatment is not. Do not induce vomiting without professional direction, especially if your dog is already wobbly (aspiration risk).
