During the Middle Ages Scottish Deerhounds were used as deer hunting dogs for Scottish tribes.
"The original purpose of the Gordon Setter was to hunt gamebirds. Their quarry in the United Kingdom may be partridge or grouse, pheasant, ptarmigan, blackgame, snipe or woodcock: whilst overseas bird dogs are worked on quail, willow grouse, sand grouse, guinea fowl, sagehen, francolin."
"Images of Brittanys were first seen on tapestries and paintings from the 17th century. These images depicted orange and white dogs hunting and retrieving game. The first written and verifiable record of Brittanys comes from a hunting description written by Reverend Davies in 1850."
