Is Xylitol Safe for Dogs?
Veterinary organisations, including the ASPCA and Pet Poison Helpline, classify xylitol as extremely toxic to dogs. Xylitol triggers a rapid release of insulin in dogs, leading to a severe drop in blood sugar (hypoglycaemia).

The Merck Veterinary Manual explains that xylitol ingestion may also cause acute liver failure, even when only small amounts are consumed.

Why Xylitol Can Be a Problem for Some Dogs
Main compounds of concern
- Xylitol, a sugar alcohol that causes:
- A rapid insulin surge in dogs
- Dangerous hypoglycaemia
- Potential liver injury or liver failure
Portion size and dog size
Even extremely small amounts can cause serious toxicity. Smaller dogs are at even higher risk because a tiny dose can have a large effect relative to body weight.
Preparation differences
Xylitol appears in many products, including:
- Sugar-free chewing gum
- Sugar-free peanut butter
- Baked goods
- Mints and candies
- Toothpaste and mouthwash
- Some vitamins or supplements
Veterinary organisations emphasise that all forms containing xylitol are unsafe for dogs.
Signs Reported When Dogs React Poorly to Xylitol
- Vomiting
- Weakness
- Loss of coordination
More serious signs
- Tremors
- Seizures
- Collapse
- Liver injury indicators, as noted in veterinary toxicology summaries
These signs develop quickly and may progress without prompt veterinary care.
