This is Rex. He is a full blooded Boxer. Rex loves to swim completely underwater and dive into the pool. Rex has been on TV many times, the News, Animal planet, Yahoo news all over the internet and in Seth Casteel's book titled Underwater Dogs. Rex is the only boxer in this book. Rex has been doing this for years. Were we live in Arizona in the summers it often hits 120 out. Rex found a great way to stay cool on our hot summer days! Rex loves to play and swim with kids and show off. Its a great way for him to get in his exercise with out over heating. If you LOVE his video or have any question feel free to leave a comment.
