The world appears to be divided into cat and dog lovers, but fortunately Walter Chandoha, the 20th century’s greatest pet photographer found himself happily in the middle. He loved these intriguing creatures equally for their unique beauty and individualism, and as subjects to photograph in a career spanning over 70 years. While working on his critically acclaimed TASCHEN book Cats, Chandoha handpicked his favorite dog photos for a potential follow-up title, putting into carefully marked boxes hundreds of contact sheets, prints, and color transparencies, many unseen for at least 50 years, and some totally unseen.
