In the 13th century Marco Polo reported from China that Kublai Khan of Cathay had two kivichi or Masters of the Chase, each commanding 10,000 men assisting the Khan to command a total of 5,000 dogs in tracking, hunting, and killing wildlife. Marco Polo didn’t mention how big the kennels must have been.
King Henry III of France (1575) was a devoted dog lover – perhaps a bit too devoted. He owned 2,000 dogs, so perhaps it is just as well that he had several palaces. He liked to have 100 dogs within patting distance, and he went walkabout with 20 at a time.
