Extremely Dangerous
Xylitol (often labeled as Birch Sugar) is a sugar substitute found in sugar-free gum, candies, toothpaste, and some peanut butters.
Why is it dangerous?
In dogs, Xylitol is quickly absorbed into the bloodstream and triggers a potent release of insulin from the pancreas. This causes a rapid, life-threatening drop in blood sugar (hypoglycemia).
Symptoms
Symptoms can occur within 15-30 minutes:
- Vomiting
- Weakness and staggering (loss of coordination)
- Collapse / Seizures
- Liver failure (can occur days later)
Action: This is a true emergency. If you suspect your dog ate Xylitol, do not wait for symptoms. Go to an emergency vet immediately.
