Seth Casteel is a photographer, writer, and animal activist, but he’s perhaps best known for his photos of dogs diving underwater for toys. And why not? These pics are wonderful!

If you’ve ever played around with your pooch in a pool or in the ocean, you know you’ve seen these goofy faces before.

Enjoy and be sure to check out Casteel’s books and calendars that are for sale HERE.
