Sometimes dogs refuse to eat over simple matters, such as a change in their food or not getting their preferred food. An upsetting event, such as a move or the serious illness or death of a member of the family, can also cause a Maltese to stop eating. Some of these behaviors are learned, unwittingly taught to the dog by doting owners. It's so easy to spoil a tiny, cheerful dog such as a Maltese, but it doesn't turn out well for dog or human. Maltese are subject to hypoglycemia if they don't eat enough. Hypoglycemia is low blood glucose, which can happen suddenly and can be fatal. Loss of appetite can lead to hypoglycemia, but it can also be a symptom of hypoglycemia.
