Master of the Buckhounds

The Master of the Buckhounds was an officer in the Master of the Horse's department of the British Royal Household. The holder was also His/Her Majesty's Representative at Ascot. It was a political office, so the holder, who was always a nobleman, changed with every change of government. The office was abolished by the Civil List Act 1901.  (A buckhound is smaller than a staghound and used for coursing the smaller breeds of deer, especially fallow deer.)
Masters of the (Privy) Buckhounds
The Privy Buckhounds were created in 1536 to provide for a hunting pack overseen by a Royal appointee rather than a hereditary officer.
