Award-winning lifestyle pet photographer Seth Casteel is passionate about showcasing animals in their natural surroundings. And when are dogs happier, but swimming and playing fetch? In this unique gallery of “Underwater Dogs,” Casteel captures all the best and spontaneous elements of pups in the water. Wide-eyed and mouths agape, these little guys will do just about anything to get that ball. Check out the photos below!

Casteel’s talent is not limited to just pets, he’s photographed celebrities too! Ellen DeGeneres, Perez Hilton, and even the cast of Twilight have been featured in his photos. Casteel’s “Underwater Dog” art has been compiled into a book of the same name, releasing October 23. The book is available for pre-order now on Amazon.
