underwater_dogs.jpgThe real doggy paddle: The pets taking the plunge with their underwater  antics

With a look of steely determination, these pets perfect their doggy paddle as they dive head first into a swimming pool to retrieve their beloved ball.

Anyone with a dog will know the lengths it will go to fetch something thrown for it. And these heart-warming images show nothing stands in their way - not even water.

These canine warriors pounce into the pool with their eyes firmly fixated on the prize.

Some of them bare their teeth, others open their eyes as wide as possible while one or two get caught up in a frenzy of bubbles.

These images are the handiwork of photographer Seth Casteel, who has captured the moment the water dogs take the plunge....

...Based in Los Angeles and Chicago, Seth's photography agency specialises in lifestyle pet photography, embracing the 'at-ease' mentality of pets on location in the natural surroundings.

He enjoys working with animals whether he's on location in Beverly Hills photographing a pampered pooch or volunteering at the local shelter taking pictures of dogs and cats to give them a better chance of finding homes.
