Can dogs eat xylitol?

Toxic: call for help

Short answer: No. Xylitol is poisonous to dogs, even in small amounts, and it hides in sugar-free baking.

Also called or found in: birch sugar, wood sugar, sugar-free baking sweetener

Why it matters

In dogs, xylitol triggers a fast, strong release of insulin that can drop blood sugar sharply. People don't react this way. (FDA)

The Merck Veterinary Manual links doses above about 100 mg per kg of body weight to low blood sugar, and doses above about 500 mg per kg to liver injury in some dogs.

Low blood sugar can start within 10 to 60 minutes (FDA). With some products, like gum, Merck says it can be delayed 12 to 18 hours. Liver injury may not show for a day or two.

What owners may notice

Vomiting, weakness, wobbling or stumbling, tiredness, collapse and seizures (FDA, Merck).

Later, liver injury can cause yellowing of the gums or eyes and abnormal bleeding (ASPCA, Merck).

This list can't tell you if your dog is OK. Only a veterinarian can.

If your dog ate some

Call your veterinarian or an animal poison line now: ASPCA Animal Poison Control Center (888) 426-4435 or Pet Poison Helpline (855) 764-7661. Have the package, the amount and your dog's weight ready. Don't try home remedies unless your veterinarian or the poison line tells you to.

In the kitchen

Granulated xylitol is sold for sugar-free baking. Never use it in anything a dog could reach, and keep sugar-free cakes, cookies, muffins and frostings off low counters.
