Moscow Water Dog: The Moscow Water Dog, also known as the Moscow Diver, Moscow Retriever or Moskovsky Vodolaz, is a little-known dog breed derived from the Newfoundland, Caucasian Shepherd Dog and East European Shepherd.  It is now extinct, but was used in the development of the  Black Russian Terrier.  The Moscow Water Dog was produced only by the Red Star Kennels, the state operated organization chartered to provide working dogs for the armed services.

German Shepherd: The German Shepherd (German: Deutscher Schäferhund , ] ) is a breed of medium to large-sized working dog that originated in Germany.  The breed's officially recognized name is German Shepherd Dog in the English language (sometimes abbreviated as "GSD").  The breed is also known as the Alsatian in Britain and Ireland.  The German Shepherd is a relatively new breed of dog, with their origin dating to 1899.  As part of the Herding Group, German Shepherds are working dogs developed originally for herding sheep.  Since that time however, because of their strength, intelligence, trainability, and obedience, German Shepherds around the world are often the preferred breed for many types of work, including disability assistance, search-and-rescue, police and military roles, and even acting.  The German Shepherd is the second-most registered breed by the American Kennel Club and fourth-most registered breed by The Kennel Club in the United Kingdom.

Airedale Terrier: The Airedale Terrier (often shortened to "Airedale"), also called Bingley Terrier and Waterside Terrier, is a dog breed of the terrier type that originated in the valley ("dale") of the River Aire, in the West Riding of Yorkshire, England.  It is traditionally called the "King of Terriers" because it is the largest of the terrier breeds.  The Airedale was bred from the Old English Black and Tan Terrier (now extinct), the Bull Terrier, the Otterhound and probably some other Terrier breeds, originally to serve as an all around working farm dog.  In Britain this breed has also been used as a war dog, guide dog and police dog.  In the United States, this breed has been used to hunt big game, upland birds, and water fowl, and serve in many other working capacities.

Alaunt: The Alaunt is an extinct breed of dog, with the original breed having existed in central Asia and Europe from ancient times through the 17th century.  The Alaunt breed had three distinct phenotypes: Alaunt Veantre, Alaunt Boucherie and the Alaunt Gentile.  They all were large, short coated dogs of varying head-types.  The former two resembled the molosser type dogs much like the present-day Dogo Argentino or like the Caucasian Shepherd Dog except with short hair and a mesocephalic head which made them excellent large-game hunters.  The Alaunt was originally bred by the Alani tribes, the nomads of Indo-European Sarmatian ancestry who spoke an Iranian language.  The Alans were known as superb warriors, herdsmen, and breeders of horses and dogs.  The Alans bred their dogs for work and developed different strains within the breed for specific duties.  The breed was further developed in Spain, France, Germany, England, and in Italy.

Chiribaya Dog: The Chiribaya Dog (Spanish: "perro Chiribaya" ) or Peruvian shepherd dog ("perro pastor Peruano ") was a pre-Columbian breed of dog from the southwest of Peru, identified by the 42 mummies discovered by anthropologist Sonia Guillén Oneglio in the Ilo District, Moquegua Region, on the south coast of Peru.  It has been established that it was a llama herding dog.  The dogs were not only an important part of the social structure of the ancient Peruvians, but they received special treatment after death as well.  The dog variety has been referred to in various Spanish-language documentaries under different terms, such as "el perro pastor Chribaya" ('the Chiribaya shepherd dog') and "pastor Peruano " ('Peruvian shepherd'), though the ancient Peruvians did not keep sheep.  Its original name is unknown.  (It has been referred to more ambiguously by the term "perro Peruano " or "perro del Perú " ('Peruvian dog', 'dog of Peru'), but this has also been applied to an extant but ancient hairless variety, referred to in more detail as "perro sin pelo del Perú", 'hairless dog of Peru', or the Peruvian hairless dog, a favorite in South American dog shows.)

Cesky Terrier: The Cesky Terrier ( ; Czech: "Český teriér", literally "Bohemian Terrier" or "Czech Terrier") is a small terrier type dog originating in Czechoslovakia.

Caucasian Shepherd Dog: The Caucasian Shepherd Dog (Adyghe: Хьэпарий, "Khʹèparij", Адыгэ Мэлыхъуэхьэ, "Adygè Mèlykhʺuèkhʹè" ; Karachay-Balkar: Басхан Парий, "Baskhan Parij" ; Armenian: Կովկասյան հովվաշուն, "Kovkasyan hovvašun" ; Azerbaijani: "Qafqaz çoban iti" ; Georgian: კავკასიური ნაგაზი, "Kavkasiuri nagazi" ; Turkish: "Kafkas Çoban Köpeği" ; Ossetian: Аргъонахъ, "Arghonaq" ; Russian: Кавказская овчарка, "Kavkazskaya ovčarka" ) is a large breed of dog that is popular in Russia, Armenia, Azerbaijan, and Georgia.  It is extremely popular in Georgia, which has always been the principal region of penetration of Caucasian shepherd dogs.  The official standard of this breed is fundamentally based on the dogs taken from Georgia.

Teddy Roosevelt Terrier: The Teddy Roosevelt Terrier is a small to medium-sized American hunting terrier.  Lower-set with shorter legs, more muscular, and heavier bone density than its cousin the American Rat Terrier.  There is much diversity in the history of the Teddy Roosevelt Terrier breed and it shares a common early history with the American Rat Terrier, Fox Paulistinha and Tenterfield Terrier.  It is said the Rat Terrier background stems from the terriers or other dogs that were brought over by early English and other working class immigrants.  Since the breed was a farm, hunting and utility dog there was little to no planned breeding other than breeding dogs with agreeable traits to each other in order to produce the desired work ethic in the dog.  It is assumed that the Feist (dog), Bull Terrier, Smooth Fox Terrier, Manchester Terrier, Whippet, Italian Greyhound, the now extinct English White Terrier, Turnspit dog and or Wry Legged Terrier all share in the Teddy Roosevelt Terrier's ancestry.  These early Ratting Terriers were then most likely bred to the Beagle or Beagle cross bred dogs (for increased scenting ability) and other dogs.  Maximizing the influences from these various breeds provides the modern Teddy Roosevelt Terrier with a keen sense of awareness and prey drive, an acute sense of smell and a very high intellect.  Although they tend to be aloof with strangers they are devoted companion dogs with a strong desire to please and be near their owners side at all times.

Cropping (animal): Cropping is the removal of part or all of the pinnae or auricles, the external visible flap of the ear, of an animal; it sometimes involves taping to make the ears pointy.  Most commonly performed on dogs, it is an ancient practice that was once done for perceived health, practical or cosmetic reasons.  In modern times, it is banned in many nations, but is still legal in a limited number of countries.  Where permitted, it is seen only in certain breeds of dog such as the Pit bull, Miniature Pinscher, Doberman Pinscher, Schnauzer, Great Dane, Boxer, Caucasian Shepherd Dog and Beauceron.

Georgian Shepherd: The Georgian Shepherd (Georgian: ქართული ნაგაზი "qartuli nagazi") is a molosser-type livestock guardian breed of dog with ancient working origins in the Georgia Caucasus.  The Georgian shepherd is related to the Caucasian Shepherd Dog.  There are two kinds of Georgian mountain dog: the short haired Kazbegian dog, also called "Nagazi", and the long haired Georgian mountain dog.
