Can dogs eat xylitol?

Toxic — do not feed
No, xylitol is extremely toxic to dogs even in small amounts.

Why

Xylitol, also labeled birch sugar, is a sugar substitute found in sugar-free gum, mints, peanut butter, toothpaste, and many sugar-free foods. In dogs it is rapidly absorbed and triggers a massive insulin release, causing a dangerous drop in blood sugar within 30 minutes to 2 hours. Lower doses cause hypoglycemia, while higher doses can cause liver failure.

Warning signs to watch for

Weakness, staggering, vomiting, hypoglycemia, seizures, and liver failure; contact a vet or pet poison helpline immediately.
