Xylitol is a sugar-substitute found in lots of human sweets, medicines and gums. It's poisonous to all dogs. Symptoms of xylitol poisoning usually develop within an hour. They can rapidly become life-threatening.

In 2020 alone, the Pet Poison Helpline received around 6000 calls from worried owners whose dogs had eaten things that contained xylitol, especially sugar-free gum. Symptoms of poisoning happen because xylitol triggers a sharp drop in blood sugar and life-threatening liver damage at high doses. Outlook depends on how much your dog has eaten and how quickly they see a vet.
