Doofus, Dog of Doom

"Every time he howls - something dies!"
Doofus is a sad, black, abandoned puppy adopted from the dogs' home. But it soon becomes obvious to his new owner Holly and her animal-mad friend Clive that Doofus is no ordinary dog. Not only do his howls seem to cause dreadful things to happen - but then terrifying creatures from the past start to invade their village. How can Clive and Holly hold them back? And can Doofus really be a fearsome dog of ancient legend?
