Up in Heaven — Emma Chichester Clark

Daisy is Arthur's dog, and she's devoted to him. But she's very old, and lately she's finding it hard to keep up with Arthur. One night, after she goes to sleep as usual, she wakes up in heaven. Heaven is a wonderful place, and Daisy loves it there. But she knows Arthur is sad and misses her. So Daisy finds a way to let Arthur know she's happy -- and that's the first step toward making him happy again, too.
