Seth Casteel's Underwater Dogs: The Poolside Series That Made a Photographer Famous

A chance encounter with a dog named Buster in 2012 gave Seth Casteel the concept behind Underwater Dogs, the series of poolside portraits that brought the American photographer international recognition. Each image catches a dog mid-dive, plunging toward a ball, with muzzle distorted, cheeks inflated and eyes wide in what reads as an extraordinary adventure. Casteel's commercial animal photography runs alongside a substantial commitment to promoting shelter adoptions, and the same instinct shapes this body of work: he does not stage the perfect pose but leaves room for play and unpredictability, turning a simple plunge into a compact portrait of each animal's character. The results are funny, at moments nearly surreal, and above all spontaneous, revealing a side of the animals rarely visible in daily life. In Casteel's own words, dogs share an emotional range comparable to that of humans, yet unlike people they remain always spontaneous. The series is published at sethcasteel.com and the photographer maintains an Instagram presence at @sethcasteel; images are credited to sethcasteel.com.
