It's so cold outside, on the freezing streets of Manhattan. Yet the dogs must have their walks. They are city dogs, after all, and it takes an army of dog-walkers to get these beasts out of the apartments at regular intervals. We headed up to Central Park West to meet America's most pampered canines, all dressed up in their winter coats. Here's our first NYC dog of winter, in his red knitted sweater. It's Oliver, the French Bulldog!
