Will a dog stop eating after ingesting xylitol gum?

A dog that eats xylitol-containing gum may lose its appetite. Xylitol in gum is dangerous to dogs and is mainly found in sugar-free gum, mints, vitamins, and some toothpastes. Some brands contain only a little, so just a few pieces can cause severe hypoglycemia; for reference, some gums have 0.2 g per piece, meaning a 10-pound dog needs only two pieces to reach a potentially toxic dose. Gum also risks choking or intestinal blockage and can upset the stomach causing refusal to eat, so dogs should not chew xylitol gum..
