Question: The Poitevin and Border Terrier breeds were both created for what use?
Context: The Border Terrier is a small, rough-coated breed of dog in the terrier group.  Bred as a fox and vermin hunter, the Border Terrier shares ancestry with the Dandie Dinmont Terrier and the Bedlington Terrier. The Glen of Imaal Terrier () is a breed of dog of the terrier category and one of four Irish terrier breeds.  It is sometimes called the Irish Glen of Imaal Terrier or the Wicklow Terrier, and the name of the breed is often shortened by fanciers to just Glen. Old Jock (1859–1871), was a Fox Terrier famous during the late 19th and early 20th centuries.  A mostly white dog, he ran briefly with a hunting kennel before becoming a show dog, most notably with a victory at the show which popularised the Fox Terrier.  His main show rivalry was with a dog named Tartar, and along with a dog named Trap, the three were popular sires of the Fox Terrier breed.  He was also involved in the early formation of the Jack Russell Terrier and the Dandie Dinmont Terrier breeds. The Patterdale Terrier is an English breed of dog descended from the Northern terrier breeds of the early 20th century.  The origins of the breed can be traced back to the Lake District, specifically to Ullswater Hunt master Joe Bowman, an early Border Terrier breeder. The Poitevin, known as the Chien de Haut-Poitou until 1957, is a breed of dog used in hunting as a scenthound, from the province of Poitou.  This predominantly pack hound was created in the 17th century specifically to hunt wolves. The Irish Terrier () is a dog breed from Ireland, one of many breeds of terrier.  The Irish Terrier is considered one of the oldest terrier breeds.  The Dublin dog show in 1873 was the first to provide a separate class for Irish Terriers.  By the 1880s, Irish Terriers were the fourth most popular breed in Ireland and Britain. A terrier is a dog of any one of many breeds or landraces of terrier type, which are typically small, wiry, very active and fearless dogs.  Terrier breeds vary greatly in size from just 2 lb to over 70 lb and are usually categorized by size or function.  There are five different groups with each group having several different breeds. 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 Kerry Blue Terrier (also known as the Irish Blue Terrier) () is a breed of dog.  Originally bred to control "vermin" including rats, rabbits, badgers, foxes, otters and hares, over time the Kerry became a general working dog used for a variety of jobs including herding cattle and sheep, and as a guard dog.  Today the Kerry has spread around the world as a companion and working dog.  Despite a Kerry Blue winning Crufts (the most important UK dog show) in 2000, it remains an "unfashionable" breed, and is distinctly uncommon; however, it not as threatened as some of the other terrier breeds such as Skye Terrier, Sealyham Terrier, and Dandie Dinmont Terrier. 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.
