The Drentsche Patrijshond is a versatile spaniel-type hunting dog from the Dutch province of Drenthe.
 Called the Dutch Partridge Dog (or "Drent" for Drenthe) in English, approximately 5,000 dogs are registered with the breed club in the Netherlands, and breed clubs operate in Belgium, Denmark, Scandinavia and North America.
 The Drentsche Patrijshond bears some resemblance to both spaniel and setter types of dog.
 An excellent pointer and retriever, this dog is often used to hunt fowl and adapts equally well to the field or marshes.
The French Spaniel (Epagneul Français) is a breed of dog of the Spaniel-like setter.
 It was developed in France and Canada as a hunting dog, descended from dogs of the 14th century.
 Popular with royalty during the Middle Ages, it nearly became extinct by the turn of the 20th century but was saved by the efforts of Father Fournier, a French priest.
 One of the largest breeds of Spaniel, it typically has a white coat with brown markings.
 It is a friendly breed that has few health issues, but can be affected by a syndrome called acral mutilation and analgesia.
 The breed is recognised by Canadian and international kennel clubs but not by The Kennel Club (UK).
 The American Kennel Club has included the breed in its Foundation Stock Service, the first step to full recognition.
Charles Alfred Cruft (28 June 1852 – 10 September 1938) was a British showman who founded the Crufts dog show.
 Charles first became involved with dogs when he began to work at Spratt's, a manufacturer of dog biscuits.
 He rose to the position of general manager, and whilst working for Spratt's in France he was invited to run his first dog show at the 1878 Exposition Universelle.
 After running dog shows in London for four years, he ran his first Cruft's dog show in 1891, and continued to run a further 45 shows until his death in 1938, as well as running two cat shows in 1894 and 1895.
 He was involved in a range of dog breed clubs, including that for Schipperkes, Pugs and Borzois.
 He and his wife upheld a story that they never owned a dog, and instead owned a cat, however Cruft admitted to owning at least one Saint Bernard in his memoirs, published posthumously.
The Irish Red and White Setter () is a breed of dog, more specifically a setter.

The German Spaniel, also known as the Deutscher Wachtelhund (German quail dog), is a breed of dog that was developed in Germany around 1890, and is used as a hunting dog.
 Descended from the old German breed, the Stoeberer (lit.
 "rummager"), which became popular with commoners following the Revolutions of 1848 in the German states, who required a versatile hunting dog.
 Stoeberer is now a type of hunting dog in Germany with the Wachtelhund being its sole member.
 The breed is not very well known outside of Germany, but was recognised by the United Kennel Club in 1996.
The Irish Setter (Irish: "sotar rua" , literally "red setter") is a setter, a breed of gundog, and family dog.

Gos Rater Valencià (English for: Valencian rat hunting dog) is a breed of dog that originates in Spain.

 It is a traditionally docked breed.
The Polish Hunting Dog, or formerly Polish Scenthound (Polish: "Gończy Polski" ) is a breed of scent hound originating in Poland.
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.
