Terrier Group is the name of a breed Group of dogs, used by kennel clubs to classify a defined collection of dog breeds.
 In general, a "Terrier Group" includes one particular type of dog, the Terrier, although other types may be included in a kennel club's "Terrier Group".
 Most major English-language kennel clubs include a "Terrier Group" although different kennel clubs may not include the same breeds in their "Terrier Group".
 The international kennel club association, the Fédération Cynologique Internationale, includes Terriers in Group 3 "Terrier", which is then further broken down into four "Sections" based on the type of terrier and breed history.
Fox Terriers are two different breeds of the terrier dog type: the Smooth Fox Terrier and the Wire Fox Terrier.
 Both of these breeds originated in the 19th century from a handful of dogs who are descended from earlier varieties of British terriers, and are related to other modern white terrier breeds.
 In addition, a number of breeds have diverged from these two main types of fox terrier and have been recognised separately, including the Jack Russell Terrier, Miniature Fox Terrier and Rat Terrier.
 The Wire and Smooth Fox Terriers share similar characteristics, the main differences being in the coat and markings.
 They have been successful in conformation shows, more prominently in America than their homeland.
Szwajcaria Kaszubska ("Kaszëbskô Szwajcariô", Kashubian and German: "Kaschubische Schweiz" ) (literally: "Kashubian Switzerland") - is the northern region of the Kashubian Lake District.
 In the region of the Kashubian Switzerland is located the highest point in the Polish Lowland ("Niż Polski") - Wieżyca (329 metres above sea level).
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.
The Polish Lowland Sheepdog (Polish: "Polski Owczarek Nizinny" , also PON), is a medium-sized, shaggy-coated, sheep dog breed native to Poland.
The Scottish Terrier (also known as the Aberdeen Terrier), popularly called the Scottie, is a breed of dog.
 Initially one of the highland breeds of terrier that were grouped under the name of "Skye Terrier", it is one of five breeds of terrier that originated in Scotland, the other four being the modern Skye, Cairn, Dandie Dinmont, and West Highland White Terriers.
 They are an independent and rugged breed with a wiry outer coat and a soft dense undercoat.
 The First Earl of Dumbarton nicknamed the breed "the diehard".
 The modern breed is said to be able to trace its lineage back to a single female, named Splinter II.
Zelazna is a breed of sheep and is also known by "Zeleznienska".
 The Zelazna was developed at Warsaw Agricultural University.
 They belong to the Polish Lowland group and are found throughout Poland.
 They were developed from Polish Merino crossed with Leicester Longwool and Lowicz.
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.
The Brazilian Terrier, is a breed of dog developed in Brazil.
 It is one of several terriers probably descended from the combining of the Fox Terrier with other small breeds.
Cryoconservation of animal genetic resources is a strategy wherein samples of animal genetic materials are preserved cryogenically.
 Animal genetic resources, as defined by the Food and Agriculture Organization of the United Nations, are "those animal species that are used, or may be used, for the production of food and agriculture, and the populations within each of them.
 These populations within each species can be classified as wild and feral populations, landraces and primary populations, standardised breeds, selected lines, varieties, strains and any conserved genetic material; all of which are currently categorized as Breeds."
 Genetic materials that are typically cryogenically preserved include sperm, oocytes, embryos and somatic cells.
 Cryogenic facilities are called gene banks and can vary greatly in size usually according to the economic resources available.
 They must be able to facilitate germplasm collection, processing, freezing, and long term storage, all in a hygienic and organized manner.
 Gene banks must maintain a precise database and make information and genetic resources accessible to properly facilitate cryoconservation.
 Cryoconservation is an "ex situ" conservation strategy that often coexists alongside "in situ" conservation to protect and preserve livestock genetics.
 Cryoconservation of livestock genetic resources is primarily done in order to preserve the genetics of populations of interest, such as indigenous breeds, also known as local or minor breeds.
 Material may be stored because individuals shared specific genes and phenotypes that may be of value or have potential value for researchers or breeders.
 Therefore, one of the main goals remains preserving the gene pool of local breeds that may be threatened.
 Indigenous livestock genetics are commonly threatened by factors such as globalization, modernization, changes in production systems, inappropriate introduction of major breeds, genetic drift, inbreeding, crossbreeding, climate change, natural disasters, disease, cultural changes, and urbanization.
 Indigenous livestock are critical to sustainable agricultural development and food security, due to their: adaptation to environment and endemic diseases, indispensable part in local production systems, social and cultural significance, and importance to local rural economies.
 The genetic resources of minor breeds have value to the local farmers, consumers of the products, private companies and investors interested in crossbreeding, breed associations, governments, those conducting research and development, and non-governmental organizations.
 Therefore, efforts have been made by national governments and non-governmental organizations, such as the Livestock Conservancy, to encourage conservation of livestock genetics through cryoconservation, as well as through other "ex situ" and "in situ" strategies.
 Cryogenic specimens of livestock genetic resources can be preserved and used for extended periods of time.
 This advantage makes cryoconservation beneficial particularly for threatened breeds who have low breed populations.
 Cryogenically preserved specimens can be used to revive breeds that are endangered or extinct, for breed improvement, crossbreeding, research and development.
 However, cryoconservation can be an expensive strategy and requires long term hygienic and economic commitment for germplasms to remain viable.
 Cryoconservation can also face unique challenges based on the species, as some species have a reduced survival rate of frozen germplasm.
