Rolf (died 1919) [1] was an Airedale terrier that was claimed to have been able to perform arithmetic and communicate with humans on an intellectual level.
According to Rolf's owner, Paula Morkel of Mannheim, Germany, the dog could communicate with humans by tapping out letters with his paw. He assigned the highest number of taps to less common letters. [1] According to Morkel, the dog was a poet, [2] a bibliophile [3] and a 'speaker' of several languages. [2] In her biography of Rolf she even claimed that the dog dabbled in deep theology and philosophy. [3] These claims attracted attention in Germany, as they came at the height of the 'New Animal Psychology' movement. [4] The 'New Animal Psychologists', led by Dr. Karl Krall, believed that certain animals, such as dogs and horses, were nearly as intelligent as humans and could be trained to unlock their intellectual potential. [5] A colleague of Krall's, Professor H.E Ziegler of the University of Stuttgart, studied Rolf at his home and came away impressed, [4] as did a Dr. William McKenzie. [3] However, a study by doctors Wilhelm Neumann and Ferdinand Lothar concluded that Rolf was merely reacting to unconscious signals from his master. [6] According to an article published in Psychology Today , the Rolf case proved influential in developing the Nazi talking dog programme. [5]
Pit bull is an umbrella term for several types of dog believed to have descended from bull and terriers. In the United States, the term is usually considered to include the American Pit Bull Terrier, American Staffordshire Terrier, American Bully, Staffordshire Bull Terrier, and sometimes the American Bulldog, along with any crossbred dog that shares certain physical characteristics with these breeds. In other countries, including the United Kingdom, the term is used as an abbreviation of the American Pit Bull Terrier breed specifically, while the Staffordshire Bull Terrier is not considered a pit bull. Most pit bull-type dogs descend from the British bull and terrier, a 19th-century dog-fighting type developed from crosses between the Old English Bulldog and the Old English Terrier.
The Airedale Terrier, 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 and the Otterhound and probably some other Terrier breeds, and has contributed to other dog breeds, such as the Yorkshire Terrier.
The Staffordshire Bull Terrier, also called the Staffy or Stafford, is a purebred dog of small to medium size in the terrier group that originated in the northern parts of Birmingham and in the Black Country of Staffordshire, for which it is named. They descended from 19th-century bull terriers that were developed by crossing bulldogs with various terriers to create a generic type of dog generally known as bull and terriers. Staffords share the same ancestry with the modern Bull Terrier, although the two breeds developed along independent lines, and do not resemble each other. Modern Staffords more closely resemble the old type of bull terrier, and were first recognised as a purebred dog breed by The Kennel Club of Great Britain in 1935.
Greyfriars Bobby was a Skye Terrier or Dandie Dinmont Terrier who became known in 19th-century Edinburgh for spending 14 years guarding the grave of his owner until he died on 14 January 1872. The story continues to be well known in Scotland, through several books and films. A prominent commemorative statue and nearby graves are a tourist attraction.
A police dog, also known as a K-9, is a dog that is trained to assist police and other law enforcement officers. Their duties may include searching for drugs and explosives, locating missing people, finding crime scene evidence, protecting officers and other people, and attacking suspects who flee from officers. The breeds most commonly used by law enforcement are the German Shepherd, Belgian Malinois, Bloodhound, Dutch Shepherd, and Labrador Retriever. In recent years, the Belgian Malinois has become the leading choice for police and military work due to their intense drive, focus, agility, and smaller size, though German Shepherds remain the breed most associated with law enforcement.
The Welsh Terrier originates from Wales and was originally bred for hunting fox, rodents and badger; but during the last century, it has mainly been bred for showing. Despite this, it has retained its terrier strength of character. The Welsh Terrier has been claimed to be the oldest existing dog breed in the UK.
The Black Russian Terrier, also known as the Chornyi Terrier, is a breed of dog created in USSR in Red Star Kennel during the late 1940s and the early 1950s for use as military/working dogs. At the present time, the Black Russian Terrier is a breed recognized by the FCI, AKC, CKC, KC, ANKC, NZKC and other cynological organizations. The contemporary Black Russian Terrier is a working dog, guarding dog, sporting and companion dog.
The American Staffordshire Terrier, also known as the AmStaff, is a medium-sized, short-coated American dog breed recognized by the American Kennel Club, but not the United Kennel Club, which instead allows American Staffordshire Terriers to be registered under the American Pit Bull Terrier breed.
The Tibetan Terrier is a medium-sized breed of dog that originated in Tibet. Despite its name, it is not a member of the terrier group. The breed was given its English name by European travelers due to its resemblance to known terrier breeds. The Tibetan name for the breed, Tsang Apso, roughly translates to "shaggy or bearded ("apso") dog, from the province of Tsang". Some old travelers' accounts refer to the dog as Dokhi Apso or "outdoor" Apso, indicating a shaggy or bearded working dog which lives outdoors.
A bark is a sound most often produced by dogs. Other animals that make this noise include, but are not limited to, wolves, coyotes, foxes, seals, frogs, and barking owls. "Bark" is also a verb that describes the sound of many canids.

A talking animal or speaking animal is any non-human animal that can produce sounds or gestures resembling those of a human language. Several species or groups of animals have developed forms of communication which superficially resemble verbal language, however, these usually are not considered a language because they lack one or more of the defining characteristics, e.g. grammar, syntax, recursion, and displacement. Researchers have been successful in teaching some animals to make gestures similar to sign language, although whether this should be considered a language has been disputed.
The Telomian is a type of dog found in isolated villages near the Telom River in the rainforests of the Malay Peninsula. It has been introduced into the United States. Some US-based breeders were selling these dogs as pure breds, which was dismissed with the Malaysian Kennel Association in a statement that these are pariah dogs and not a breed.
Jan Bondeson is a Swedish-British rheumatologist, scientist and author, working as a senior lecturer and consultant rheumatologist at the Cardiff University School of Medicine. He has also written non-fiction on topics such as medical anomalies and unsolved murders. In 2003 he told an interviewer, "I've always had a profound interest in history, especially the history of medicine, and a bit of a fancy for the macabre and odd." Bondeson is the biographer of a predecessor of Jack the Ripper, the London Monster, who stabbed 50 women in the buttocks, of Edward "the Boy" Jones, who stalked Queen Victoria and stole her underwear, and Greyfriars Bobby, a Scottish terrier who supposedly spent 14 years guarding his master's grave.
The Intelligence of Dogs is a 1994 book on dog intelligence by Stanley Coren, a professor of canine psychology at the University of British Columbia. The book explains Coren's theories about the differences in intelligence between various breeds of dogs. Coren published a second edition in 2006.
The Hundesprechschule Asra or Tiersprechschule Asra was an institution for performing dogs that existed in Leutenberg, Thuringia, Germany, from 1930 until near the end of World War II. Its Nazi talking dogs became a popular topic in the English-speaking press in 2011, when Jan Bondeson's Amazing Dogs: A Cabinet of Canine Curiosities used it as an example of Nazi-sponsored animal research.
Human–canine bonding is the relationship between dogs and humans. This relationship can be traced back to at least 15,000 years ago, to the Bonn-Oberkassel dog, who was found buried alongside two humans. For centuries, dogs have been considered man's best friend. This is most evident in western countries, such as the United States, where 44% of households have a pet dog.
