It's nighttime and Mr. Krup's dog exclaims that she loves looking at the moon. Mr. Krup, who adores his dog more than anything else, suddenly starts building a rocket ship and one day disappears off into outer space. When he finally returns from his mysterious mission, he has a special gift to give to his dog . . .

In this mischievously comical tale from one of Sweden's most beloved children's authors, readers will delight in the absurdity of this dog-human friendship, and perhaps even see themselves reflected in Mr. Krup's irrational devotion to his furry friend.
