Go to a vet now
If the gum is sugar-free, treat it as an emergency. Many sugar-free gums contain xylitol, which can drop a dog's blood sugar within 10-60 minutes and cause liver failure at higher doses. Regular sugar gum is not toxic but can cause a blockage in small dogs.
What to do right now
- Check the package for xylitol (or birch sugar) and count how many pieces are missing.
- Use the xylitol toxicity calculator to estimate the dose.
- If there is any xylitol, call your vet or poison control right away, or go straight to an emergency vet.
- If your dog is weak, wobbly or collapsing, rub a little honey or corn syrup on the gums and drive to the vet immediately.
- Bring the gum packaging with you.
Why gum can be dangerous for dogs
Xylitol triggers a massive insulin release in dogs, causing dangerously low blood sugar (hypoglycemia). Doses of about 0.1 g/kg cause hypoglycemia, and above 0.5 g/kg can cause acute liver failure. Gum can contain up to about 1 g of xylitol per piece.
Symptoms to watch for
- Vomiting
- Weakness, wobbliness or lethargy
- Trembling
- Collapse
- Seizures
- Later (24-72 hours): yellow gums, bruising, vomiting (liver failure)
What not to do
- Do not wait for symptoms: treatment works best before signs start.
- Do not induce vomiting at home if your dog is weak or wobbly.
What the vet will do
Your vet will check blood sugar, may induce vomiting if your dog is still normal, give IV dextrose and liver protectants, and monitor blood sugar and liver values for 24-72 hours.

Dog ate gum: FAQ
How much gum is toxic to a dog?
With high-xylitol gum, half a piece can poison a 10 lb dog and about 2 pieces a 50 lb dog. Brands vary, so treat any xylitol gum as an emergency.
My dog ate gum with no xylitol. What should I do?
Sugar gum is not toxic. Watch for vomiting, constipation or straining over the next 1-2 days, which could mean a blockage, especially in small dogs or if a whole pack was eaten.
My dog ate chewing gum off the floor. Is that dangerous?
Already-chewed gum has less xylitol, but it may still contain some. Call your vet if you know or suspect it was sugar-free.
