Jack Russell was a real guy. John Russell was born in Dartmouth, England in 1795, and over the years he became quite a hunting enthusiast. While he was studying to become a clergyman at Oxford, he met a milkman who had a white terrier bitch named Trump who seemed to be the perfect dog for fox hunting. After convincing the milkman to sell him the dog, Russell began breeding Trump to develop a line of terriers with the stamina to hunt foxes all day and the courage to go after game that had slipped into holes.
