PHOTOS: Dogs Who Look Like Grumpy Old MenTom Cohen's new book features crotchety canines doing their best Walter Matthau


The muse behind comedy writer Tom Cohen's book is not just furry and adorable. "My dog Piper inspired me to write the book. She's a cross between a shih tzu and a lhasa apso, and has an old lady face," Cohen tells PEOPLE. "Since I'm a comedy writer, it made sense to write some captions to go along with their amazing faces." Behold, our favorite shots from Dogs with Old Man Faces: Portraits of Crotchety Canines, a book filled with pictures of canine curmudgeons.
