Once there was a boy who wanted something to take care of. Something of his very own. He begged his mother for a puppy. Until she said YES! The boy loved his puppy. He fed him and played with him and cuddled him. But soon, the dog wanted something to take care of - something of his very own. So the dog gets a pet cat, then the cat gets a pet bird, the bird gets a pet worm, the worm gets a pet flea . . . . and on and on it goes as utter chaos ensues. This charming picture book cleverly captures a universal wish - to love and care for something - and shows that you're never too little to share in that dream.
