Dogs have appeared in art for thousands of years: The ancient Egyptians depicted their pups in frescoes. Meanwhile, Aztec artists often featured the xoloitzcuintli (the Mexican hairless dog) in their work.
Now, a group exhibition in New York is honoring how the tradition has continued into the 20th and 21st centuries. "Dog Days of Summer," which is now open at the Timothy Taylor Gallery, is all about man's best friend.
