What to Do If Your Dog Eats Xylitol

How Dangerous Is Xylitol for Dogs?

Xylitol is one of the most acutely toxic substances dogs can ingest. Even small amounts can cause life-threatening hypoglycemia (dangerously low blood sugar) within 30–60 minutes of ingestion. Larger amounts can cause acute liver failure. This is a true emergency — do not wait for symptoms.

Where Is Xylitol Found?

Xylitol is a sugar substitute found in many products:

Sugar-free gum (most common source — even 1–2 pieces can be dangerous for small dogs)
Sugar-free candy and mints
Peanut butter (check labels — some brands use xylitol)
Toothpaste and mouthwash
Vitamins and supplements
Baked goods made with xylitol
Some medications
Nasal sprays

Always check labels — xylitol may be listed as "birch sugar" or "birch extract."

What to Do Immediately

Go to the emergency vet NOW — do not wait for symptoms
Call while driving: ASPCA Poison Control (888) 426-4435 or Pet Poison Helpline (855) 764-7661
Bring the packaging so the vet can confirm xylitol content and amount
Do not induce vomiting unless specifically directed — xylitol acts very quickly

Signs of Xylitol Toxicity

Hypoglycemia signs (within 30–60 minutes):

Vomiting
Weakness and wobbling
Disorientation or confusion
Tremors or seizures
Collapse

Liver failure signs (12–24 hours later with larger doses):

Jaundice (yellow gums or skin)
Vomiting
Lethargy
Bleeding disorders

Treatment

Treatment involves IV dextrose (glucose) to correct hypoglycemia, liver protectants, and supportive care. Dogs treated promptly before symptoms develop have the best outcomes. Dogs that develop liver failure have a much more guarded prognosis.
