Katie is a small white and brown dog with a big, big heart, and when her owner brings home three tiny kittens, she is overjoyed. “Katie loved those kittens so much. As soon as she saw them, she howled, 'AROOOOOO! AROOOO!’ ” But Katie’s howling terrifies the kittens, and when her owner admonishes her, Katie curls up into a little ball of sadness. It’s one misstep after another for Katie in this funny, warmhearted picture book that ultimately ends with tail-wagging bliss. Author and artist John Himmelman conveys Katie’s moods—from exuberant enthusiasm to abject misery and back again—in marvelously expressive illustrations that are an essential part of this irresistible tale.
