Question: Which dog is bigger? The Dandie Dinmont Terrier or The Rottweiler?
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. 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. 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. The Rottweiler ( or , ) is a breed of domestic dog, regarded as medium-to-large or large.  The dogs were known in German as "Rottweiler Metzgerhund" , meaning Rottweil butchers' dogs, because their main use was to herd livestock and pull carts laden with butchered meat to market.  This continued until the mid-19th century when railways replaced droving.  Although still used to herd stock in many parts of the world, Rottweilers are now also used as search and rescue dogs, as guide dogs for the blind, as guard dogs and police dogs. 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. The Bedlington Terrier is a breed of small dog named after the mining town of Bedlington, Northumberland in North East England.  Originally bred to hunt vermin in mines, the Bedlington Terrier has since been used in dog racing, numerous dog sports, as well as in conformation shows and as a companion dog.  It is closely related to the Dandie Dinmont Terrier, Whippet and Otterhound. A Dandie Dinmont Terrier is a small Scottish breed of dog in the terrier family.  The breed has a very long body, short legs, and a distinctive topknot of hair on the head.  A character in Sir Walter Scott's novel "Guy Mannering" has lent the name to the breed, with Dandie Dinmont thought to be based on James Davidson, who is credited as being the originator of the modern breed.  Davidson's dogs descended from earlier terrier owning families, including the Allans of Holystone, Northumberland. 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. 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 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.
