Can dogs eat chewing gum?
The full picture
Chewing gum is actually the most common cause of xylitol poisoning in dogs in the UK and US. Most sugar-free gum — Orbit, Trident, Extra, Wrigley's — contains xylitol, which triggers rapid hypoglycaemia in dogs. A single piece of gum can contain 0.3–1 g of xylitol, potentially fatal to a dog under 10 kg. Even sugared gum isn't safe: the base and artificial sweeteners can upset stomachs, and the gum itself can cause an intestinal blockage. Treat any gum ingestion as a possible xylitol emergency.
If your dog has already eaten chewing gum
Call your vet or the Animal PoisonLine on 01202 509000 IMMEDIATELY — do not wait for symptoms. Most sugar-free gum contains xylitol, and symptoms of xylitol poisoning (vomiting, weakness, wobbliness, collapse) can begin within 10-30 minutes as blood sugar crashes. Bring the packet if you have it so the vet can check for xylitol on the ingredients list. Even one piece can be dangerous for a small dog.
Risks to watch for
- Xylitol poisoning (rapid, potentially fatal)
- Intestinal blockage from the gum itself
- Aspartame in some varieties
Safe portion size
None.
Safer alternatives
- Dog-safe dental chews
While you're checking what your dog can safely eat, make sure their flea and worm protection is up to date too.
