My Dog Ate Xylitol
Xylitol exposure in dogs is a true emergency because even small amounts can cause dangerously low blood sugar, seizures, liver injury, or death. Here's what to do right now, what symptoms to watch for, and when emergency care is needed.
This is a veterinary emergency.
If your dog ate xylitol or a product that may contain it, call a veterinarian or Pet Poison Helpline right away and head to an emergency clinic if your dog is vomiting, weak, trembling, seizing, or collapsing.

If your dog has consumed xylitol and is showing severe symptoms — such as vomiting, tremors, seizures, or collapse — they may need in-person emergency veterinary care immediately. If this is the case, we recommend calling our partner Pet Poison Helpline ($85 consultation fee). They work directly with your emergency vet to guide treatment and help resolve your pet's case faster.
When to call a vet
Go to the ER now
- ● Your dog ate any known or suspected xylitol product, including sugar-free gum, candy, peanut butter, baked goods, toothpaste, chewable vitamins, melatonin products, or medications.
- ● Your dog is vomiting, weak, sleepy, shaky, disoriented, having tremors, seizures, or has collapsed.
- ● You do not know how much was eaten, when it happened, or whether the product contained xylitol.
- ● Your dog is very small, a puppy, or may have eaten multiple pieces of gum or multiple tablets.
See a vet within 24 hours
- ● Your dog seems normal but definitely ate a xylitol-containing product within the last several hours.
- ● You found torn packaging and suspect exposure, even if you did not witness it.
- ● Your dog ate a product labeled 'sugar free' and you are not sure whether xylitol is one of the ingredients.
Watch at home, call if it worsens
- ● Do not monitor at home without first speaking to a veterinarian or poison expert. Dogs can look normal early on and still become critically ill.
- ● After a veterinarian advises home monitoring, watch closely for vomiting, lethargy, weakness, tremors, poor coordination, or behavior changes and call your vet if anything changes.
What Happened & Why It's Dangerous
It can drop blood sugar fast
In dogs, xylitol can trigger a large insulin release that rapidly lowers blood sugar. This can happen soon after ingestion and may become life-threatening.
Liver injury can follow
Some dogs develop severe liver damage after xylitol exposure, especially at higher doses. Liver injury may not be obvious right away, which is why veterinary monitoring matters.
Many common products contain it
Xylitol is found in sugar-free gum, candies, some peanut butters, baked goods, toothpaste, mouthwash, nasal products, supplements, and chewable medications.
Symptoms can escalate quickly
Early signs may include vomiting and lethargy, but dogs can progress to weakness, tremors, seizures, collapse, or signs of liver failure without prompt treatment.
What to Do Right Now
Stay calm and act quickly. Remove any remaining product from your dog's reach and collect the package, ingredient list, strength, flavor, and estimated amount eaten. Call your veterinarian, an emergency veterinary hospital, or Pet Poison Helpline right away for case-specific advice. Do not give food, home remedies, or try to induce vomiting unless a veterinarian specifically tells you to do so. If your dog is showing symptoms such as vomiting, weakness, tremors, seizures, or collapse, go to the nearest emergency clinic immediately.
