Question: Do both the Kintamani and Alpine Mastiff still exist?

Context paragraphs:
Kintamani (dog): The Kintamani is a dog native to the Indonesian island of Bali.  It is a popular pet for the Balinese and locally Bali's only official breed and efforts are currently under way to have the dog accepted by the Federation Cynologique Internationale as a recognized breed.  It is an evolving breed indigenous to the Kintamani region which evolved from the local Bali street dogs, which are rather a feral random-bred landrace distinctive to Bali.

Exhibition Boxing Bouts: Exhibition Boxing Bouts is the possible title for a very early American television series.  Aired 1931 to 1932 in New York City, it consisted of miniature boxing matches, and aired on what was then mechanical television station W2XAB, which later became WCBS-TV.  Time-slots varied from 15 minutes to 30 minutes, and it aired without commercials, as United States television was still an experimental service.  According to the section ""Radio Dial Log"" in the August 20, 1931 edition of "The New York Sun", one of the episodes featured a description by Harry Von Zell and Bill Schudt Jr, with Jimmie deForrest as the referee.  None of the episodes still exist, as it aired live, and practical methods to record live television did not exist until late 1947.  A still photograph of the series appears in page 19 of the February 20, 1932 edition of "The New York Sun", depicting two boxers in a small ring.

English Mastiff: The English Mastiff is a breed of extremely large dog (often known simply as the Mastiff) perhaps descended from the ancient Alaunt and Pugnaces Britanniae, with a significant input from the Alpine Mastiff in the 19th century.  Distinguishable by enormous size, massive head, and a limited range of colours, but always displaying a black mask, the Mastiff is noted for its gentle and loving nature.  The lineage of modern dogs can be traced back to the early 19th century, but the modern type was stabilised in the 1880s and refined since.  Following a period of sharp decline, the Mastiff has increased its worldwide popularity.  Throughout its history, the Mastiff has contributed to the development of a number of dog breeds, some generally known as Mastiff-type dogs, or, confusingly, just as "Mastiffs".

Womyn's land: Womyn's land is a term which refers to women-only communes organized by women, for women.  These communities mainly exist in rural areas where land is bought, and then utilized, to establish a closed-off matriarchal society without the presence of males.  They became popular during the 1970s throughout the time of the Radical Feminist movement, however, there are many that still exist today.  Womyn's lands practice lesbian separatism; an idea which emerged as a result of the Radical Feminist movement in the late 1960s.  Lesbian separatism is based on the idea that women must exist separately from men, socially and politically, in order to achieve a true feminist or lesbian utopia.  The Radical Feminist group Cell 16 is often credited for establishing the base of ideas that define lesbian separatism.  These separatist communities exist as a way for women to achieve female liberation by separating themselves from mainstream patriarchal society.  Men are not allowed to live in, or enter these communities.  Most communities go as far as banning male infants and/or male relatives.  Womyn's lands, as well as lesbian separatism, have generated a wide range of criticisms.  These criticism center around, but are not limited to, the lack of acceptance by many of bisexual and heterosexual women; and the exclusion of transgender and transsexual women for not being biological females.  Examples of present-day Womyn's lands include Hawk Hill Community Land Trust, HOWL, and Sugar Loaf Women's Village.  Today, these communities are facing decline as well as the struggle to connect with younger generations of women.

Alpine Mastiff: The Alpine Mastiff is an extinct Molosser dog breed, the progenitor of the St. Bernard, and a major contributor to the modern Mastiff (through such dogs as "Couchez"), as well as to other breeds that derive from these breeds or are closely related to them.  M.B. Wynn wrote, "In 1829 a vast light brindle dog of the old Alpine mastiff breed, named L'Ami, was brought from the convent of Great St. Bernard, and exhibited in London and Liverpool as the largest dog in England."  William Cavendish, 5th Duke of Devonshire, is believed to have bred Alpine Mastiffs at Chatsworth House.

On Stage, Everybody: On Stage, Everybody was a United States television variety show which was produced by ABC, but aired on DuMont Television Network station WABD.  Broadcast in 1945, it appears to have been one of several early television series produced for WABD so that ABC production crews could get experience in television program production, as ABC did not yet have a TV station of its own.  The emcee on the series was Danton Walker.  Notably, the Hall Johnson Choir made a guest appearance in one of the episodes.  As methods to record live television did not exist until late 1947, none of the episodes still exist.

Ice age: An ice age is a period of long-term reduction in the temperature of Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers. Within a long-term ice age, individual pulses of cold climate are termed "glacial periods" (or alternatively "glacials" or "glaciations" or colloquially as "ice age"), and intermittent warm periods are called "interglacials".  In the terminology of glaciology, "ice age" implies the presence of extensive ice sheets in both northern and southern hemispheres.  By this definition, we are in an interglacial period—the Holocene—of the ice age.  The ice age began 2.6 million years ago at the start of the Pleistocene epoch, because the Greenland, Arctic, and Antarctic ice sheets still exist.

Pittsburg, Colorado: Pittsburg is a former mining town from the late 19th century located about 9 miles north of Crested Butte, Colorado.  While Pittsburg is sometimes considered a ghost town, none of the original structures still exist.  The only cabins that still exist in the area were built after 1973 and are strictly summer vacation homes, as the area is inaccessible by cars during the winter.

Grace Yeager: Grace Yeager is the assumed title of a 1931–1932 United States television series which aired on New York City television station W2XAB.  Among the earliest regularly-scheduled series, it featured the singer of the same name, who was a soprano.  According to an article in the October 31, 1931 edition of The New York Sun titled "W2XAB Source of Features", Yeager had previously been a member of the San Carlos Opera Company.  None of the episodes still exist, as it aired live, and practical methods to record live television did not exist until 1947.

Professional wrestling weight classes: In professional wrestling, a weight class is a standardized weight range for the wrestlers.  The top class in almost every promotion is heavyweight, but super heavyweights exist.  Weight class matches in modern-day American professional wrestling are rare, but weight class championships still exist.  However, Japanese professional wrestling, Mexican wrestling and British wrestling use the weight classes more seriously.
