Why
In dogs, xylitol can cause a rapid, dangerous drop in blood sugar. Some dogs also develop severe liver injury; how this happens is not yet known. Sugar-free gum is the most common source, and the amount of xylitol can differ even between flavours of one brand.
Signs to watch for
- Vomiting
- Weakness and tiredness
- Wobbly walking, loss of coordination
- Seizures
- Signs of low blood sugar can start within 30 minutes
What to do
Contact your vet or a pet poison helpline as soon as you realise your dog ate something with xylitol. Note the product and how much was eaten. Don't wait for signs, and don't give anything by mouth unless your vet tells you to.
