Meet Jack-Jack, the coolest dog in the world! A new series of adventures with short chapters, narrated by Jack-Jack himself, featuring black and white illustrations. After taking care of baby chimpanzees in Africa, Jack-Jack enjoys his new home until the arrival of the "chickens" in the yard marks the end of quiet mornings and brings him a new set of challenges. He is convinced that Ronnie, the rooster, is determined to bother him. Is he being irrational, or is this naughty chicken actually against him? Luckily, Jack has so much to do, like searching for fossils in a real mammoth grave and appearing on TV with a special thermal camera to see how fit he is, so that a rooster won't bother him.
