The boy who ate dog biscuits / Sachs, Betsy

Billy Getten, a boy who is so eager to have a dog that he eats dog biscuits, falls madly in love with a stray taken in by the local veterinarian, and now faces the task of convincing his parents that he is responsible enough to be a dog owner.

All Billy wants is a dog of his own, but he gets a baby sister instead.
