Can dogs have xylitol?

Not safe — toxic
No. Xylitol triggers a rapid, dangerous drop in blood sugar and can cause liver failure in dogs — it's a true emergency.

Xylitol is a sugar substitute in sugar-free gum, mints, some peanut butters, baked goods, and toothpaste. Even small amounts are dangerous to dogs and act fast — within 15–30 minutes.
