Wide eyed with barely contained excitement and blowing bubbles through their little noses, these swimming puppies could bring a smile to the most dour of faces.
The images are the handiwork of award-winning photographer Seth Casteel, who has captured the moment the puppies break through the surface of the water to stunning effect.
The result is a collection of over 80 portraits, as Casteel seeks to capture a unique side to man's best friend.

Says Seth Casteel: 'My series of underwater photos show a side of puppies we never get to see.

'Most of the puppies featured in this book hadn't been underwater until they met me, and some had never even been swimming!'
