Step 1: Calculate Total Xylitol Consumed
Find the packaging. Xylitol content is listed in grams per piece. Calculate: grams per piece × pieces eaten. This determines whether hypoglycemia risk (0.1g/kg) or liver failure risk (0.5g/kg) threshold is crossed.

Step 2: Call Poison Control and Go to Emergency Vet
📞 <strong>ASPCA Poison Control:</strong> (888) 426-4435. Do NOT wait for symptoms — hypoglycemia can cause death within hours. Xylitol is absorbed rapidly.

Step 3: Do NOT Induce Vomiting Without Vet Approval
⚠️ If instructed to induce at home, use hydrogen peroxide (1 tsp per 5lbs). But go to vet ASAP — xylitol may need IV dextrose to prevent hypoglycemia.

Step 4: Prepare for Hospitalization
Your vet will: induce vomiting (if early), give activated charcoal, start IV dextrose, and monitor blood glucose for 24 hours. Liver enzymes will be checked for 72 hours. Early treatment has 80%+ survival.
La science derrière
Le xylitol est un alcool de sucre (polyol) qui déclenche une libération rapide et exagérée d'insuline par les cellules bêta canines — jusqu'à à 6-7 fois la quantité libérée par le glucose. Cela s'explique par le fait que les chiens métabolisent le xylitol via la même voie que le glucose mais avec une cinétique différente. L'hypoglycémie qui en résulte (glycémie <60mg/dL) provoque un dysfonctionnement neurologique, des convulsions et la mort. À des doses plus élevées (>0,5g/kg), le xylitol provoque une nécrose hépatique aiguë par épuisement de l'ATP et stress oxydatif. Le mécanisme est dépendant de la dose et unique aux chiens — les chats semblent moins sensibles (ASPCA, 2023).
Questions fréquentes
How much xylitol is toxic to dogs?
Xylitol is toxic to dogs at doses as low as 0.1g/kg for hypoglycemia and 0.5g/kg for liver failure. A single piece of sugar-free gum can contain 0.3-1.0g of xylitol — meaning ONE piece can cause severe hypoglycemia in a small-to-medium dog. Emergency treatment is needed even for tiny amounts.
What are the symptoms of xylitol poisoning in dogs?
Symptoms appear within 10-60 minutes (sometimes delayed 12 hours): vomiting, lethargy, weakness, collapse, tremors, seizures, and coma — these result from hypoglycemia (low blood sugar). Liver failure symptoms (jaundice, coagulopathy) may be delayed 12-72 hours. Even small amounts cause dangerously low blood sugar.
Why is xylitol toxic to dogs but not humans?
In dogs, xylitol is rapidly absorbed and triggers a massive insulin release from the pancreas — 6-7x more than glucose would. This causes profound hypoglycemia. Humans do not have this insulin response. Additionally, xylitol causes dose-dependent hepatocellular necrosis in dogs through mechanisms not seen in humans.
What products contain xylitol?
Xylitol is found in: sugar-free gum, mints, peanut butter (some brands), toothpaste, mouthwash, nasal sprays, chewable vitamins, baked goods, ice cream, and "birch sugar" sold as a sweetener. Some brands: Trident, Orbit, Ice Breakers, Eclipse. Always check ingredient lists before giving human food to dogs.
Can a dog survive xylitol poisoning?
Yes, with immediate treatment. If caught within 30 minutes, induced vomiting prevents absorption. If hypoglycemia has begun, IV dextrose corrects blood sugar. Even with liver damage, aggressive hospital care (IV fluids, liver protectants, plasma transfusions) has 70-80% survival if treatment begins within 8 hours. Delayed treatment has worse prognosis.
