How much is safe?
None. Xylitol is never safe for dogs - not even a little.
There is no safe amount of xylitol for a dog. It should never be within a dog's reach in any form. Because it is so potent, even a single piece of sugar-free gum or a spoonful of xylitol-sweetened peanut butter can be a genuine emergency for a small dog.
Symptoms to watch for
Signs can appear within 15 to 30 minutes and include weakness, wobbliness, vomiting, collapse and seizures as blood sugar plummets. Liver damage may follow over the next day or two, causing further vomiting, lethargy and jaundice. This is a fast, serious poisoning.
Think they have eaten Xylitol?
Contact your vet or an emergency line immediately if your dog eats anything containing xylitol, even a small amount, and even if they seem fine. This is a true emergency where minutes count - do not wait for symptoms to appear before ringing for advice.

What happens
Xylitol is a sugar substitute that is harmless to people but extremely dangerous to dogs. In a dog it triggers a rapid release of insulin, which causes blood sugar to crash within minutes, and larger amounts can cause liver failure. It is one of the fastest-acting toxins a dog can encounter, and it takes only a small amount to be dangerous.

Common questions
What foods contain xylitol?
Sugar-free gum, mints and sweets, some peanut butters, protein bars, low-sugar baked goods, and even some toothpastes and medicines. It is sometimes labelled birch sugar. Always check the label of anything sugar-free before it goes near your dog.
How quickly does xylitol affect dogs?
Very quickly - blood sugar can crash within 15 to 30 minutes, causing weakness, collapse or seizures. Larger amounts can lead to liver failure over the following day or two. Treat any exposure as an emergency.
My dog ate sugar-free gum - what should I do?
Call your vet or an emergency line immediately, even if your dog seems fine. Sugar-free gum often contains xylitol, and prompt treatment before symptoms start gives the best chance of a good outcome.
