In celebration of the world?s favorite animal, we bring you over 400 photographs of or about dogs. With pictures from the 19th century to today, the collection includes works by Man Ray, Eric Fischl, Wolfgang Tillmans, Donna Ruskin, Fatima NeJame, Vincent Versace, and of course Elliott Erwitt and William Wegman. Together, their pictures, unique in style but united in canine affection, are testimony if ever there was one that dogs are not only best friends, but also pure photographic inspiration.
