'Charlie and his family will soon be moving into their new house. His parents have promised him a puppy - a small, bouncy, bright-eyed puppy. Nothing at all like Crusher, the dog who guards the construction site. At first, Charlie is scared and doesn't want anything to do with the big, barking black-brown dog. But over time he begins to realise that Crusher doesn't want to be scary, and he's not really suited to being a guard dog. Could he be the dog for Charlie, after all?' (Publication summary)
