Question: Which of these breeds is now extinct and was never established, the Toy Bulldog or Wirehaired Vizsla?

full_context: Document 1: Toy dog: Toy dog traditionally refers to a very small dog or a grouping of small and very small breeds of dog. A toy dog may be of any of various dog types. Types of dogs referred to as toy dogs may include Spaniels, Pinschers and Terriers that have been bred down in size. Not all toy dogs are lapdogs, although that is an important and ancient type of toy dog. The very smallest toy dogs are sometimes called "teacup" size, although no major dog registry recognizes that term.
Document 2: Polish Hound: The Polish Hound, commonly known as Ogar Polski, is a breed of hunting dog indigenous to Poland. The Polish Hound has a keen sense of smell. This heightened sense combined with the endurance needed to hunt in harsh environments led to its use in hunting, while its stature made it popular with Polish nobility.
Document 3: Wirehaired Pointing Griffon: The Wirehaired Pointing Griffon (also called the Korthals Griffon , and the Griffon d'arrêt à poil dur Korthals in France and Quebec) is a breed of dog used in hunting as a gundog. It is sometimes considered to be Dutch in ancestry, due to the nationality of the breed founder, Eduard Karel Korthals. History records the progression of the development of the breed through Biebeshein am Rhen Germany where the founder established the Ipenwoud kennel and the breed type was established and then into France where it is now recognized. Others consider the Griffon to be a German breed because Korthals' kennel, Ipenwoud, was located in Biebesheim am Rhein, Germany. It was there for over twenty years that Korthals dedicated his life to the development and perfection of the Korthals Griffon.
Document 4: Kuvasz: The Kuvasz (] ), is an ancient breed of a livestock dog of Hungarian origin. Mention of the breed can be found in old Hungarian texts. It has historically been used as a royal guard dog, or to guard livestock, but has been increasingly found in homes as a pet over the last seventy years.
Document 5: Wirehaired Vizsla: The Wirehaired Vizsla ( ; ] ; English plural: Vizslas or sometimes Vizslak, based on the Hungarian plural vizslák ] ), is a dog breed originating in Hungary. Wirehaired Vizslas are known as excellent hunting dogs, and also have a level personality making them suited for families. The Wirehaired Vizsla is a versatile, natural hunter endowed with an excellent nose and an above average trainability. Although they are lively, gentle mannered, demonstrably affectionate and sensitive, they are also fearless and possessed of a well-developed protective instinct. The breed has a firmness on point, is an excellent retriever, and has the determination to remain on the scent even when swimming. The overall appearance embodies the qualities of a multi-purpose pointing dog, endurance, working ability and an easily satisfied nature. This is a dog of power and drive in the field, yet is a tractable and affectionate companion in the home.
Document 6: Bull Terrier (Miniature): The Bull Terrier (Miniature) is a breed with origins in the extinct English White Terrier, the Dalmatian and the Bulldog. The first existence is documented 1872 in "The Dogs of British Island".
Document 7: Toy Fox Terrier: The Toy Fox Terrier is a small terrier breed of dog, directly descended from the larger Fox Terrier but considered a separate breed.
Document 8: Toy Manchester Terrier: The Toy Manchester Terrier is a breed of dog, categorized as a terrier. The breed was bred down in size in North America from the Manchester Terrier, and is placed in the Toy Group by the American Kennel Club and the Canadian Kennel Club (the Manchester Terrier is placed in the Terrier Group.) Neither the Fédération Cynologique Internationale nor The Kennel Club recognize a Toy variety of the Manchester Terrier.
Document 9: Korthals: The dog, the Korthals Griffon, known as the Wirehaired Pointing Griffon
Document 10: Vizsla: The Vizsla is a dog breed originating in Hungary, which belongs under the FCI group 7 (Pointer group). The Hungarian or Magyar Vizsla are sporting dogs and loyal companions, in addition to being the smallest of the all-round pointer-retriever breeds. The Vizsla's medium size is one of the breed's most appealing characteristics as a hunter of fowl and upland game, and through the centuries the Vizsla has held a rare position among sporting dogs – that of household companion and family dog.
Document 11: Toy Trawler Spaniel: The Toy Trawler Spaniel is an extinct breed of Spaniel which physically was similar to the King Charles Spaniel of the 16th century. It is considered to have descended from the original King Charles Spaniel, and the older variety of Sussex Spaniel. It was originally used as a sporting dog, but became used as a toy and show dog. It was considered to be on the verge of extinction by 1920. A preserved specimen is kept in Tring at the Natural History Museum.
Document 12: Toy Bulldog: The Toy Bulldog is an extinct dog breed that existed in England at 18th and early 19th centuries. Breeders were working in two different directions to create this breed. One was to downsize the Bulldog. This was not very successful due to complications with breeding sub-regular size dogs of this breed together. The dwarf size Bulldog puppies were and still are occasionally born out of regular size parents, but they were neither the healthiest, nor the most fertile dogs. They often produced regular-size puppies. Thus, this version of the breed had never been established.
Document 13: Transylvanian Hound: The Transylvanian Hound (Hungarian: "erdélyi kopó" , also known as the Transylvanian Scent Hound or Hungarian Hound) is an ancient dog breed of Hungary, historically primarily used for hunting. It is a strong, medium-sized scent hound, characterized by a black body, with tan and sometimes white markings on the muzzle, chest and extremities, and distinctive tan eyebrow spots. It has a high-pitched bark for a dog of its size. The breed was rescued from extinction by focused breeding efforts in the late 20th century. There were formerly two varieties, the long-legged and short-legged, developed for different kinds of hunting in the Middle Ages. Only the long-legged strain survives.
Document 14: Rare breed (dog): Rare breed (dog) is any breed of dog that is small in number and is used to refer to both old established breeds such as the Stabyhoun and Glen of Imaal Terrier or newer creations. Since dogs have greater genetic variability than other domesticated animals the number of possible breeds is vast with new crosses constantly occurring, from these both selected and random crosses may come new breeds should offspring reliably breed true to type. New breeds from the wild such as the Carolina Dog are quite rare compared to attempts at breed creation from man as found in the American Hairless Terrier which sought to exploit a mutation.
Document 15: Leavitt Bulldog: The Leavitt Bulldog is a late 20th-century re-creation of the now extinct Old English Bulldog, the original bulldog breed which existed around the 19th century Regency era, about 1820. In contrast to English bulldogs of modern times, depictions of the breed from nearly two centuries earlier showed healthier, more agile dogs, with working ability. Unlike the 19th century breed however, the Leavitt Bulldog has a placid temperament. It is one of several breeds developed in order to overcome the genetic problems in the English Bulldog breed. The Leavitt Bulldog was developed by breeder David Leavitt which he originally named the Olde English Bulldogge. Leavitt has since disassociated himself with this name for the breed and set up the Leavitt Bulldog as its name due to many later OEB litters losing many of the qualities of his original OEB litter. David Leavitt's "Leavitt Bulldogs" were purebred from the earlier Olde English Bulldogge stock. Regardless of this, the original name has been adopted by the United Kennel Club whose breed standard is adopted as of 1 January 2014. The Leavitt Bulldog was mentioned in the documentary "Pedigree Dogs Exposed – Three Years On" as a suggested healthier alternative to the English Bulldog.
