Question: can 1 piece of gum kill a dog?
Answer: Since a piece of sugarless gum can have between 0.3 and 1 gram of xylitol, it will only take a few pieces to poison a dog. There are 190 grams of xylitol in 1 cup of the sweetener. This means that if a recipe for 12 cupcakes call for a cup of xylitol, a 50-lb. pup can become ill after eating one cupcake!
