The Forever Dog by Bill Cochran is great. It is about a child who has grown up with a dog and his dog gets sick and dies. The boy and his dog had made a promise to each other to be together "forever" and the boy is upset because he feels like his dog broke his promise when he died. The boy is very sad but finally realizes his dog didn't break his promise afterall as he lives on forever in the boy's heart.
