'Daisy was devoted to Arthur.' 'Devoted' is an unusual word to describe a dog in a children's book, but devoted Daisy undoubtedly is. She is also old and sick, and when she dies, she goes to heaven - a wonderful doggy heaven where she is young again and has lots of friends. But she sees that Arthur is desperately unhappy at losing her. So she gives him a series of dreams wherein he sees her happiness and understands that she would be glad for him to have a new puppy. When Maisy arrives, Daisy surveys the two of them with pleasure. Clark's glowing colours shimmer and gleam with sadness and happiness. A book to treasure, which will provide abundant reassurance.
