🐱 Can cats eat this? →Why
This sugar-free sweetener (found in gum, mints, some peanut butters, baked goods and supplements) triggers a massive insulin release in dogs — 3 to 7 times normal — causing a rapid, dangerous drop in blood sugar. Higher doses can cause life-threatening liver failure.
How much matters
Hypoglycaemia can occur above ~0.1 g/kg (100 mg/kg); liver failure above ~0.5 g/kg (500 mg/kg). With concentrated gum, as few as 1–2 pieces can poison a small dog. Signs can start within 30 minutes.
Signs of trouble to watch for
- Weakness or collapse
- Vomiting
- Loss of coordination
