Greyhound jockeys or monkey jockeys are capuchin monkeys trained to ride racing dogs for sport over a 5/16 mile course.
The use of monkeys as jockeys in greyhound races was recorded in Sydney at the Shepherd's Bush Race course in Mascot, in Sydney, Australia in 1927. and 1928. Monkey jockeys were still being used in greyhound races in Victoria Australia in 1938.
In the United States, monkey Greyhound racing is claimed to have begun as a fad in Palm Beach, Florida in 1930 with the concept conceived by Loretta and Charlie David. The couple obtained 12 female capuchin monkeys and over a period of two years trained them to ride Greyhound racing dogs in specially designed saddle harnesses. The craze continued in America until the late 1930s before the public lost interest.
