SANDRA MUELLER, who is now 23, bought her first SLR camera at 14. She has been a big animal lover since childhood - from guinea pigs to her aunt's dog, with whom she spent entire summer vacations. Today, she is the proud owner of Maja, the "most beautiful Bernese Mountain Dog mix in the world," (of course, she is in the book!) and has found her calling in photography. She specializes in portraits of people and dogs. She feels it is very important to capture the unique personality of each of her subjects, two-legged or four-legged, in each shot. Sandra Muller lives in Haimendorf (near Nuremberg), Germany.
