Your dog probably puzzles you. Most of us do that. And most of us would like to keep things as they are: humans in the dark, dogs with the upper hand. It's all in our new book, Things Your Dog Doesn't Want You To Know, as told to humans Hy Conrad and Jeff Johnson. Inside you'll find revelations such as the reason we ate the sofa (leather tastes very similar to rawhide), and what we really think of the costumes you dress us up in. I'm not alone. Ten other courageous canines have stepped forward to tell you what your dog won't - every last dirty, hairy bit of it.
