Schanuzer expert Jeri Muntis answers a listener question about how to keep the dog’s beard white. Her answer was a bit of a surprise to Emily. The Vegas-based Muntis, who raises champion miniature schnauzers and handles them in competitions ranging from obedience to agility, brought a schnauzer puppy and full-grown schnauzer and discussed tail-docking and ear-cropping, common for this breed.  Plus, an update on the tiger attack at the San Francisco Zoo and celebrating (or not) Black and Jack’s birthdays.
