There's a Dog in My Brain!

"When Danny made a wish to stay home instead of going to a family wedding, he didn't expect to end up trapped in the body of a dog! Now he's stuck with Mrs Grout who loves cleaning - and hates dogs. In fact, she hates them so much that Danny's sure she's got something horrible planned for him. Meanwhile, Dudley the dog is off on the adventure of a lifetime. He might look like a normal ten-year-old boy, but he has no idea how to behave like one. Drinking from the toilet bowl, chasing cats and licking loved ones is a sure fire way to get into Very Big Trouble"--Publisher's description
