Is Xylitol safe for Dogs?
✓ Sources checked by the Eaoae Safety Review · 2026-10-09 · Based on 3 sources
No, xylitol is extremely dangerous for dogs. Even small amounts can trigger a rapid insulin release, causing severe hypoglycemia and potentially fatal liver failure. It is found in many sugar-free gums, candies, and baked goods, so keep these items strictly out of reach.
🚨 Emergency: Yes — contact your veterinarian immediately.
💡 Why
Xylitol is a sugar alcohol that dogs metabolize differently than humans. It stimulates the pancreas to dump large amounts of insulin, leading to a dangerous drop in blood sugar. In higher doses, it causes direct damage to liver cells, resulting in acute liver failure.
🩺 What to do
- Remove any remaining xylitol-containing products from the dog's reach immediately.
- Call your veterinarian or an animal poison control center right away, even if the dog seems fine.
- Bring the packaging with you to the vet to help determine the exact dose ingested.
❓ Common questions
How much xylitol is toxic to a dog?
As little as 0.1 grams per kilogram of body weight can cause hypoglycemia, while 0.5 grams per kilogram can lead to liver failure.
What are the early signs of xylitol poisoning?
Look for sudden weakness, vomiting, lethargy, or stumbling, which usually appear within 30 minutes to a few hours after ingestion.
Is xylitol safe for cats?
Cats do not appear to be susceptible — the Merck Veterinary Manual notes xylitol does not trigger the same insulin response in cats. Keep it away from all pets anyway, but the emergency risk is to dogs.

| Source | Dogs | Cats | Dose info |
|---|---|---|---|
| ASPCA Animal Poison Control | Listed as toxic — xylitol can cause low blood sugar (hypoglycemia) and potentially liver damage depending on amount ingested; initial signs vomiting, lethargy and loss of coordination, progressing to seizures; liver damage can occur within 12-24 hours (page written for pets generally, no species split) | Listed for pets generally — same xylitol section with no cat-specific distinction or separate cat warning on this page | — |
| Pet Poison Helpline | Toxic to dogs — causes a dangerous, rapid drop in blood sugar and can also cause liver failure; any amount should be treated as a potential danger, even small amounts can potentially cause a dangerous drop in blood sugar | Not toxic in the same way — page states xylitol does not appear to cause the dangerous drop in blood sugar in cats that it causes in dogs; still advises contacting a vet/helpline because other ingredients in sugar-free products can harm cats | — |
| Merck Veterinary Manual | Toxic to dogs — xylitol toxicosis occurs in dogs; rapid dose-dependent insulin release can result in profound hypoglycemia, and some dogs develop severe hepatic insufficiency or failure | Not at risk — page states explicitly: 'Dogs are the only domestic species in which xylitol toxicosis has been reported; cats are not at risk for hypoglycemia or liver injury from xylitol toxicosis' | Dogs: >~100 mg/kg (45 mg/lb) associated with hypoglycemia; >500 mg/kg (227 mg/lb) may develop severe hepatic insufficiency or failure |
| VCA Hospitals | Extremely toxic to dogs — even small amounts can cause hypoglycemia, seizures, liver failure, or even death; lower doses cause hypoglycemia, higher doses cause liver failure | Not covered | — |
