Can dogs eat xylitol?
UnsafeNo — xylitol is one of the most acutely toxic common ingredients for dogs. Even one piece of sugar-free gum can cause seizures in a small dog within 30 minutes. Liver failure can follow 24–72 hours later. This is a true emergency.
Xylitol is a sugar substitute in many "sugar-free" products. In dogs (not humans) it triggers massive insulin release, crashing blood sugar. Higher doses also cause acute liver failure. Call your vet immediately — don't wait for symptoms.

Watch out for
- Toxic at very low doses — 0.1g/kg for hypoglycemia; 0.5g/kg for liver failure.
- One stick of sugar-free gum can contain 0.3–1g of xylitol.
- Hidden sources: sugar-free gum, some "natural" peanut butters, baked goods, human toothpaste, some medicines.
- Symptoms (weakness, staggering, seizures) can appear within 30 minutes.
- Liver damage may appear 24–72 hours later — even if the dog initially seemed fine.
Signs of poisoning
- Weakness, staggering, appearing "drunk" within 30–60 minutes
- Vomiting
- Collapse
- Tremors or seizures
- Yellow gums (jaundice) — sign of liver failure, 24–72 hours later
- Dark or black tarry stool — sign of internal bleeding
Timeline
What to do right now
1. Call your vet or the ASPCA Animal Poison Control immediately. Have the packet, your dog's weight, and estimated amount eaten.
2. If your vet can't see you within 30 minutes, drive straight to an emergency clinic — xylitol acts fast.
3. On the way, keep your dog warm and awake. If collapse or seizure occurs, drive carefully — don't try home remedies.
4. The vet will induce vomiting (if within 1–2 hours), give IV dextrose, and monitor blood glucose and liver enzymes for 24–72 hours.
What not to do
- Don't try to feed honey or sugar at home unless a vet instructs it — absorption is too slow to rescue seizures.
- Don't "wait and see" — by the time seizures start, treatment is much harder.
- Don't assume your dog is safe if they seem normal in the first hour. Liver damage can appear 24–72 hours later.

Frequently asked
What peanut butter brands contain xylitol?
Most US mainstream brands are xylitol-free, but formulas change and some "sugar-free" or US imports contain it. Always read the label every single purchase. "Birch sugar", "sugar alcohol", or "xylitol" = unsafe.
My dog ate one piece of gum — is that serious?
Yes. Call your vet immediately. One piece can cause hypoglycemia in a small dog. Even if your dog seems fine at 30 minutes, liver damage can develop over 24–72 hours.
Is xylitol toxic to cats?
Less data available, but cats appear less affected. Don't feed deliberately; call your vet if accidental exposure happens.
What symptoms should I watch for?
Weakness, staggering (drunk-like appearance), vomiting, collapse, seizures within 30–60 minutes. Later signs (1–3 days): yellow gums, dark stool, lethargy = possible liver failure.
Can I give honey to fix low blood sugar at home?
Not without vet guidance. Absorption is too slow to rescue a dog already seizing, and at-home treatment can delay proper IV dextrose. Get to the vet.
