This is Snopes-confirmed. Also be aware this is very common in sugar free food of many kinds. The retriever puppy who I know of who died of xylitol poisoning got hold of a pack of sugar-free gum.
Always good to remind folks - if it has xylitol, KEEP IT AWAY FROM DOGS! It induces profound hypoglycemia and liver failure and is life-threatening :(
