We just finished a book (an audio book) called Marley and Me. This book tells the funny, sad, and lovely tale of Marley, the world's worst dog. A young couple gets in over their head by buying a large, exuberant yellow lab. The lab is neurotic and destructive, but ends up being the perfect and only pet for them. Very heartwarming.
We recommend the book to dog-lovers (and dogs themselves) all over the world! But beware, the end of the book is very very sad. Even Sammi, who seems to have a heart of steel, wept a bit at the finale.
Quick vote: Of course we would love a book about a bad dog, being a bad dog ourselves... But we think that you would probably love it too!!!
