“Photographer Seth Casteel has definitely taken animal photography to new heights – or depths – with his hilarious photos of dogs chasing balls underwater. Casteel, who, naturally, has two dogs of his own (a mini Labradoodle and a Norwich terrier), said that he's drawn to underwater dog photography because the photos show a side of dogs that people may have never seen before.

“Over the course of several thousands of years, we've taken wolves and made them Boston terriers”, Casteel told HuffPost. “But still, at the heart of it, dogs have wild instincts. For me, it's all about seeing those wild instincts come through underwater. They're getting back to being wild. They really love being wild. And under water, they have the best chance of doing that”.
