Underwater Puppies. Just when you thought photos of dogs swimming underwater couldn't get any cuter, Seth Casteel brings us Underwater Puppies, the sequel to his national bestselling coffee table book, Underwater Dogs. Seth auditioned 1,500 puppies, many from shelters, from all over the country for this extraordinary project. Over a hundred photos featuring adorable creatures, complete with cotton-soft fur and large helpless eyes, just paddling away in a storm of bubbles are collected in this book. How ironic that through all the splashing and bursts of action, these puppies create such peaceful, surreal imagery. $21. BUY.
