Why is

Xylitol

toxic to dogs

?

This sudden insulin spike leads to a dangerous drop in blood sugar known as hypoglycaemia which can occur within 30 to 60 minutes after ingestion. In some cases xylitol also damages liver cells and can lead to acute liver failure. Dogs are far more sensitive to this substance than humans which is why foods safe for people can be life threatening to pets.
