"Griffin Bing and his friends are back- and this time, things have gone to the dogs!
After former attack dog Luthor goes berserk at a dog show, he's accused of ruining the career of the three-time national champion. Griffin has always wondered whether you could teach such a vicious dog new tricks...but he also smells a setup of some king. He feels bad for Luthor- bad enough to spring him from the pound. The only way for Luthor to make everything right is to do the unthinkable... and become the new national champion. Can Giffin Bing, The Man with the Plan, turn this beast into a beauty? Very soon, the whole world will want to know the answer."
