Why

Xylitol is a sweetener in gum, mints, candy, baked goods, some peanut butters, toothpaste and supplements. In dogs it triggers a sudden insulin release and dangerous low blood sugar, and larger amounts can cause liver damage 12–24 hours later. This is one of the fastest-acting household poisons for dogs — call immediately, even for one piece of gum.

Signs to watch for if your dog has eaten xylitol

Vomiting
Weakness, wobbliness or collapse from low blood sugar, often within 30–60 minutes
Tremors or seizures
Yellow gums or eyes and bruising if the liver is affected, usually 12–24 hours later

Signs can lag by a day or more, so no symptoms does not mean your dog is clear — call rather than watch.

What to do now

Call your vet or the ASPCA Animal Poison Control Center at (888) 426-4435 straight away. Tell them what your dog ate, roughly how much, and when, and take the packaging with you. Don't wait for symptoms — with several poisons the harm is done before a pet looks ill.

Never induce vomiting and never give any medicine unless a vet tells you to — it can do more damage than the poison. What we will and won't tell you.

Safer alternatives for dogs

Plain baby carrots or carrot sticks
Plain cooked chicken breast — no skin, no bones, no seasoning
A few blueberries or a slice of apple with the core removed
Plain canned pumpkin (not pie filling)
Plain green beans, fresh or frozen
