Bakhmull: Bakhmull is an Aboriginal Afghan Hound belonging to an ancient group of oriental sighthounds.  The Afghan Royal Family were the only humans who possessed this breed.  The bakhmull tazi (tazi means " fast running sighthound" ) is a long haired variety of sighthounds in Afghanistan.  There are two more: Luchak tazi short haired like sloughi and Khalagh tazi with moderate long hair on ears, shoulders, elbows and thighs.Bakhmull tazi has developed in the mountain areas of Mid and Central Asia - ancient Punjab, Paunchala, "Five river land".  This dog breed roots back presumably in the ancient Indian Harappa( Mohenjo Daro) civilization 2300 - 1700 B.C.  If translated from Pashto (Afghan) the word "bakhmull" means "velvet" due to its incredible silky velvet, long, ivory color hair of the coat, rather abundant and long on the whole body, because it is a mountain oriental sighthound, except the "saddle", front parts of four legs and the muzzle.  Its color is always fawn, ivory or white with a darker "saddle", thus it produces an impression of a fawn (yellowish) dog which coat color is protective khaki that matches sandstone and limestone of the Hindu Kush mountain landscape and deserts.  Following colors are not permissible: red, red with white spots, black and black with white spots.  Bakhmulls hunt the wild ram, ibex (wild mountain goat), hare, fox, wolf, jackal, wild big cats, in old times leopard, but never birds.  They are also good guards; they guard homes and flocks of sheep.  They hunt solo, in couples and rarely in packs.  Since the 1980s the centre of Bakhmull breeding is in Russia, "The Blue Dale el Bark Bakhmull" Moscow, where they are spread all over the former Soviet Republics and various regions.  The foundation stock was brought to Russia in the 70s by military men from Afghanistan.  Breed Standard for tazi BAKHMULL (aboriginal Afghan Hound) was adopted in Moscow, Russia (since Russia has become the 2nd motherland of bakhmulls) first in 1985 and later after detailed elaboration in 1997 (RFOS-RKF).

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.

Molossus (dog): The Molossus (Greek: Μολοσσὸς ) is a breed of dog from ancient southern Europe.

Serbian Hound: The Serbian Hound (Serbian: Српски гонич / "Srpski gonič" ), previously known as the Balkan Hound (Балкански гонич / "Balkanski gonič"), is a pack hunting dog breed used in Serbia.  It is red or tan with a black saddle, neck and cranium and red or tan face.  Its head is flat and sloping, its muzzle pointed, with drop ears of the usual scent hound type.  The Serbian Hound stands 17 to 21 inches (44–56 cm) in height and weighs about 44 pounds (20 kg).  It is smooth-coated and coarse-haired.

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.

Boxer (dog): The Boxer is a medium-sized, short-haired breed of dog, developed in Germany.  The coat is smooth and tight-fitting; colours are fawn or brindled, with or without white markings, and white.  Boxers are brachycephalic (they have broad, short skulls), have a square muzzle, mandibular prognathism (an underbite), very strong jaws, and a powerful bite ideal for hanging on to large prey.  The Boxer was bred from the Old English Bulldog and the now extinct Bullenbeisser which became extinct by crossbreeding rather than by a decadence of the breed.  The purpose of the crossbreeding was the wish to eliminate the excessive white color of the breed, and the necessity of producing thousands of dogs for one of the most popular breeds in the world.  The Boxer is part of the Molosser group.  This group is a category of solidly built, large dog breeds that all descend from the same common ancestor, the large shepherd dog known as a Molossus.  The Boxer is a member of the Working Group.

It is a livestock guardian that has been bred since the age of Alexander the Great for protecting livestock from carnivorous mammals including the wolf, European jackal and the brown bear in the mountainous regions of Greece, especially Epirus.

Second Battle of Artois: The Second Battle of Artois ("Deuxième bataille de l'Artois" or "Lorettoschlacht" ) from 9 May – 18 June 1915 was a battle on the Western Front during the First World War.  A German-held salient from Reims to Amiens had been formed in 1914, which menaced communications between Paris and northern France.  A reciprocal French advance eastwards in Artois could cut the rail lines supplying the German armies between Arras and Reims.  French operations in Artois, Champagne and Alsace from November–December 1914, led General Joseph Joffre, Generalissimo (Commander in Chief) and head of Grand Quartier Général (GQG), to continue the offensive in Champagne against the German southern rail supply route and to plan an offensive in Artois, against the lines supplying the German armies from the north.
