Is Xylitol Toxic to Dogs?
Deadly for dogs
Yes, very. Xylitol (sometimes listed as birch sugar) is a sweetener found in sugar-free gum, mints, candy, some peanut and nut butters, baked goods, toothpaste and chewable vitamins. In dogs it triggers a large insulin release that can drop blood sugar dangerously within 10 to 60 minutes, and larger doses can cause liver failure.
Symptoms
- Vomiting
- Weakness, wobbling, collapse
- Tremors or seizures
- Yellow gums or eyes (liver damage), sometimes a day or more later
What to do
- Treat this as an emergency — go to a vet immediately.
- Bring the package so the vet can estimate the dose.
- Check peanut butter labels before using it for treats or pills.
Cats and xylitol
Cats seem much less affected, but there is no reason to give it to them.
