The Black and Tan Virginia Foxhound is an American foxhound breed.
 It resulted of a cross breed with Bloodhounds in the 1700s.
 The breed was developed by the landed gentry in order to get a dog suitable for fox hunting.
 Besides the Black and Tan there are the Walker, Calhoun, Penn-Marydel, Goodman, July and Trigg, which all developed from similar crosses.
 The Black and Tan is believed to descend form hunting dogs imported to America by Robert Brooke in 1650.
 These hunting dogs were the ancestors of several varieties of American hounds and stayed with the Brooke family for more than 300 years.
 Afterwards French Foxhounds were bred in after George Washington received them as gifts from the Marquis de Lafayette.
 Much later, the breed's speed and stamina were improved introducing Irish Foxhounds.

Florence Nagle (26 October 1894 – 30 October 1988) was a trainer and breeder of racehorses, a breeder of pedigree dogs, and an active feminist.
 Nagle purchased her first Irish Wolfhound in 1913, and went on to own or breed twenty-one United Kingdom Champions.
 Best in Show at Crufts in 1960 was awarded to Sulhamstead Merman, who was bred, owned and exhibited by Nagle.
 She also competed successfully in field trials with Irish Setters, from the 1920s until the mid-1960s resulting in eighteen Field Trial Champions.
 The male dog who was a linchpin in the 1970s revival of the Irish Red and White Setter breed was descended from one of Nagle's Irish Setters.

The Gordon Setter is a large breed of dog, a member of the setter family that also includes both the better-known Irish Setter and the English Setter.
 Setter breeds are classified as members of either the Sporting or Gundog Group depending on the national kennel club or council.
 The original purpose of the breed 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 and any other bird that will sit to a dog—that is to say, will attempt to avoid a potential predator by concealment rather than by taking to the wing at the first sign of danger.
 It is this combination of a bird that will sit fast in front of a dog that will remain on point that makes bird dog work possible.
