Photos of Dogs Underwater Become Viral Hit

Seth Casteel knows how to bring out a dog’s wild side. The photographer has snapped surreal photos of more than 80 dogs swimming underwater, and diving into pools to chase after a tennis ball, and turned them into a new picture book, “Underwater Dogs.”

A gallery of Casteel’s pictures was posted on social news sites last year and became an instant hit. “It all has to do with emotion and expression,” he said. “People are interested in these photos because they show a side of dogs they haven’t seen before.” Click here to see one of Casteel's underwater dog photo shoots in action.
