NEW YORK — The Westminster dog show is set to take a long walk. The nation’s top pooch pageant will be held outdoors at an estate about 25 miles north of Manhattan on June 12-13 because of the pandemic, the Westminster Kennel Club said Wednesday. The shift to the Lyndhurst site along the Hudson River in Tarrytown, New York, will mark the first time in more than 100 years that best in show at Westminster hasn’t been awarded at Madison Square Garden.
