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.
