"In more than eighty portraits by award-winning pet photographer and animal rights activist Seth Casteel capture new sides of our old friends with vibrant underwater photography that makes it impossible to look away. Each image bubbles with exuberance and life, a striking reminder that even in the most loveable and domesticated dog, there are more primal forces at work. In Underwater Dogs, Seth Casteel gives playful and energetic testament to the rough-and-tumble joy that our dogs bring into our lives."
