Can Dogs Eat Xylitol (Birch Sugar)?
No. Xylitol is extremely toxic to dogs.
Xylitol (also labeled 'birch sugar') triggers a massive insulin release in dogs, causing life-threatening hypoglycemia and, at higher doses, acute liver failure.
Emergency Action Required
If your dog has ingested Xylitol (Birch Sugar), do not wait for symptoms to appear. Immediate veterinary intervention can prevent serious harm.
Why is Xylitol Dangerous?
In dogs, xylitol is rapidly absorbed and fools the pancreas into releasing a large surge of insulin. Blood sugar plummets within minutes, producing weakness, collapse, and seizures.
It hides in sugar-free gum, mints, peanut butter, baked goods, toothpaste, and many medications โ always read labels before sharing human food.
