The world’s smallest dog has one of its biggest personalities — devoted, alert and bonded fiercely to one or two people. They are portable and long-lived, but their size makes them fragile and prone to feeling threatened, so calm handling and proper socialisation are key. They often dislike cold and appreciate a coat in winter.
