Artist William Wegman and his Weimaraner muses 

For more than 40 years, artist William Wegman has been making portraits and videos of his own beloved Weimaraner dogs, which have appeared in countless publications and featured on Sesame Street and Saturday Night Live. This month, he published a career retrospective book with 300 images from his vast collection. NewsHour Weekend’s Megan Thompson visited his studio and current canines in New York.
