These photos of puppies under water will make your day

Tuesday, September 16, 2014, 3:07 PM - Animal advocate and photographer Seth Casteel has compiled a hilarious collection of adoptable (and adopted) dogs swimming underwater for his new book Underwater Puppies.

In his book, Casteel featured “dozens of adoptable and adopted puppies ... to remind people that adoption is a fantastic option when considering bringing a puppy into your life,” the Toronto Star says.

The book's "models" ranged from six weeks to six months old.

Casteel points out that prior to the shoot, each puppy received swimming lessons and was never in any danger.
