Photographer Dan Borris was walking down the street one day with a friend when she suggested that he photograph her doing yoga while her dog ran around making her crazy. Inspiration struck! Why bother with humans? Dogs should do yoga! It was in that moment that the idea of Yoga Dogs was born. After dogs were photographed, photos were digitally manipulated to recreate a variety of tricky yoga positions. But from there, the concept took off and he began including cats too. Borris sells these photos in a calendar, with proceeds going to the animal shelters where he gets his models.
