Transylvanian Hound: The Transylvanian Hound (Hungarian: "erdélyi kopó" , also known as the Transylvanian Scent Hound or Hungarian Hound) is an ancient dog breed of Hungary, historically primarily used for hunting.  It is a strong, medium-sized scent hound, characterized by a black body, with tan and sometimes white markings on the muzzle, chest and extremities, and distinctive tan eyebrow spots.  It has a high-pitched bark for a dog of its size.  The breed was rescued from extinction by focused breeding efforts in the late 20th century.  There were formerly two varieties, the long-legged and short-legged, developed for different kinds of hunting in the Middle Ages.  Only the long-legged strain survives.

Seppala Siberian Sleddog: A rare working dog breed, the Seppala Siberian Sleddog is developed for the purpose of pulling a sled in cold country.  It is a moderate-sized dog averaging 18 to 23 kg (40 to 50 pounds) weight and 56 to 58 cm (22 or 23 inches) height.  Colours and markings are considered of little importance; eyes may be brown, blue or any combination of the two colours.  Seppalas are active and energetic but very docile and trainable.

Leonhard Seppala: Leonhard "Sepp" Seppala (September 14, 1877 – January 28, 1967) was a Norwegian-born American Sled dog musher who played a pivotal role in the 1925 serum run to Nome and participated in the 1932 Winter Olympics.  Seppala introduced the work dogs used by Native Siberians at the time to the American public; the breed came to be known as the Siberian Husky in the English-speaking world.  The Leonhard Seppala Humanitarian Award, which honors excellence in sled dog care is named in honour of him.

Artois Hound: The Artois Hound is a rare breed of dog, and a descendant of the Bloodhound.  A scent hound 22-23 inches high at the withers, weighing anything between 55 and 65 pounds, it is a well constructed dog with a slow graceful gait.  It has a large, strong head, a medium-length back and a pointed tail that tends to be long and sickle-shaped.  Their ears are set at eye level; they have large prominent eyes and quite thick lips.

Chinese goose: The Chinese goose is a breed of domesticated goose descended from the wild swan goose.  Chinese geese differ from the wild birds in much larger size (up to 5–10 kg in males, 4–9 kg in females), and in having an often strongly developed basal knob on the upper side of the bill.  The knob at the top of the beak is more prominent on males than females.  By 6–8 weeks of age, the knob is already pronounced enough that it can be used for determining gender.  Chinese geese are a close cousin of the African goose, a heavier breed also descended from the swan goose.

West Siberian Laika: The West Siberian Laika or "WSL", is a breed of hunting dog and a breed of spitz type.  Russian publications indicate that the term West Siberian Laika loosely applied to hunting dogs originating with the Mansi and Khanty people in Ural and West Siberia, but there were no standards or registrations of WSL as such until 1930.  Then WWll disrupted it for a while, but "systematic breeding with registrations" resumed after the war ended, in 1946.  This was the time the breed began taking modern shape.  Before that hunters only knew of Mansi Laika and Khanty Laika.  In early 1960 many hunters in Ural still preferred the term Mansi Laika, when speaking of West Siberian Laika.  In Russian language, the term Laika originated from the word "layat" that means to bark.  The word Laika simply means "barker".  Any hunting Laika is a bark pointer (pointing at animal of interest by barking and staying with the animal ).  It is a versatile dog depending on use and environment, but in certain parts of the country they have become more specialized.

Serbian Tricolour Hound: The Serbian Tricolour Hound ("srpski trobojni gonič" or "trobojac") is a breed of dog of the hound type.  Formerly called the Yugoslavian Tricolour Hound, the name was changed for clarity after the breakup of SFR Yugoslavia in 1991.  The breed was first exhibited at shows in 1950.  At one time it was considered a variation of the Serbian Hound, but was recognised by the Fédération Cynologique Internationale as a separate breed in 1961.

Hanover Hound: The Hanover Hound is a breed of dog sometimes referred to as a Hanoverian Hound.  It is a hunting and tracking dog descended from bloodhounds of medieval times.  It was first introduced into France in the 1980s and is still a very rare breed.  It was cross-bred with the Bavarian Hound which gave rise to the Bavarian Mountain Hound.

Catahoula Cur: The Catahoula Cur is an American dog breed named after Catahoula Parish, Louisiana, United States.  Also known as the Catahoula Leopard Dog, it became the state dog of Louisiana in 1979.  The breed is sometimes referred to as the "Catahoula Hound" or "Catahoula Leopard Hound" because of its spots, although it is not a true hound but a cur.  It is also called the "Catahoula Hog Dog", reflecting its traditional use in hunting wild boar.

Afghan Hound: The Afghan Hound is a hound that is distinguished by its thick, fine, silky coat and its tail with a ring curl at the end.  The breed was selectively bred for its unique features in the cold mountains of Afghanistan.  Its local name is Tāžī Spay (Pashto: تاژي سپی‎ ) or Sag-e Tāzī (Dari Persian: سگ تازی).  Other names for this breed are "Kuchi Hound", "Tāzī", "Balkh Hound", "Baluchi Hound", "Barakzai Hound", "Shalgar Hound", "Kabul Hound", "Galanday Hound" or sometimes incorrectly "African Hound".
