Is widely described as the first person to professionalize dog walking in New York City and, by extension, in the United States. Starting in the early 1960s, he rose each morning at dawn to walk passels of clients' dogs, eventually presiding over a business in which he and two dozen assistants walked more than 150 dogs a day. He ran Jim Buck's School for dogs for 40 years.
