Dogs have been man's best friend for as long as we've been sketching on canvas. In the background, behind the table, or right at the forefront, dogs of the past peer out from paintings and sketches, frescoes and prints across art history.

Art Dog is a collection of these painted pooches, featuring works from artists across the ages and continents. Japanese prints and German oils, American sketches and Italian murals are all included. The works spans eras and styles, but as different as these dogs are, one thing shines through: the love we've always had for them.
