Oscar puppy, or the secret of a happy Christmas

Hannah dreamed about the Dalmatian puppy all her life. At first, dad and mom were not allowed, because she was too small to properly take care of the puppy. Then Hannah appeared a brother, and again it was necessary to wait. But before Christmas, a real miracle happened - the parents decided to fulfill the dream of Hannah and brought a puppy from the Dalmatians from the nursery! The dog was called an Oscar and immediately and forever fell in love.
And everything would be fine, but it turned out that Hannah’s brother was still too small and considers the puppy a lively toy. Therefore, the poor Oscar is hiding all over the house from an overly sociable boy. Can Hannah explain to his younger brother that Oscar is not a toy, and make this Christmas truly happy?
