Xylitol and dogs — common questions

Can xylitol poison a dog?

Two toxic mechanisms: hypoglycemia (~100 mg/kg) and acute liver failure (~500 mg/kg). Hypoglycemia onset can be within 30 minutes. How serious it is depends on your dog's body weight and how much they ate — use the calculator above for the exact dose and a clear severity level.

How much xylitol does it take to harm a dog?

It depends on your dog's weight, how much they ate, and the exact form. Xylitol comes in different forms (pure xylitol, sugar-free gum (per piece), xylitol-containing peanut butter, sugar-free baked goods) and the concentration varies between them, so the form matters as much as the amount. Enter the details above to get the dose in mg/kg and whether it lands in the low, moderate, high, or emergency range.

What should I do if my dog ate xylitol?

Act quickly: note your dog's weight, roughly how much they ate and when, and keep any packaging. Don't try to make them vomit unless a vet or poison line tells you to. In US, contact Pet Poison Helpline on +1-855-764-7661 (24/7) or your nearest vet straight away.
