A photograph of a dog taken from underneath on December 2016 in VA, Canada. Forget the cats, itÌs just raining dogs! A creative duo have come up with an innovative way to raise money for animal welfare; photographing dogs as youÌve never seen them before. Professional photographer Jason Kenzie and designer Tania Ryan have created a unique set of images from the underside of dogs, named The Underdogs Project. The project will be featured as a 2017 calendar, with each month belonging to a quirky canine. (Photo by The Underdogs Project/Barcroft Images)
