Every dog curled up on an American couch today, from a Chihuahua to a Great Dane, belongs to a single species, Canis lupus familiaris. Yet within that one species, hundreds of distinct breeds have come and gone over the centuries, and the roster of extinct dog breeds is longer than most owners realize. Some vanished thousands of years ago in the courts of ancient Egypt and Greece; others disappeared as recently as the 1980s, undone by shifting fashions, aggressive crossbreeding, or simple bad luck.
This rundown walks through 25 extinct dog breeds and landraces, from Argentina’s Cordoba Fighting Dog to the frostbitten history of the Argentine Polar Dog. Along the way, it traces how many of these lost dogs still live on in the bloodlines of breeds people keep as family pets across the United States right now.
| Breed | Region of Origin | Approximate Extinction Era | Modern Legacy |
|---|---|---|---|
| Bullenbeisser | Germany | 19th century | Ancestor of the Boxer |
| Alpine Mastiff | Western Alps | 1800s | Progenitor of the St. Bernard |
| Molossus | Ancient Greece | Absorbed in antiquity | Ancestor of mastiffs, Great Danes, Rottweilers |
| Talbot | England | Middle Ages | Absorbed into the Bloodhound |
| St. John’s Water Dog | Newfoundland, Canada | 1980s | Ancestor of modern retrievers |
| Paisley Terrier | Scotland | Early 1900s | Progenitor of the Yorkshire Terrier |
| Turnspit Dog | England | Circa 1900 | None; a kitchen-wheel specialist |
| Salish Woolly Dog | Pacific Northwest | 19th century | None; a wool-producing specialist |
| Kurī | New Zealand | 19th century | Absorbed by European dogs |
| Cordoba Fighting Dog | Argentina | Mid-20th century | Ancestor of the Dogo Argentino |
Pro Tip: If a modern breed’s history mentions “extinct ancestor” or “no longer recognized type,” it’s worth digging into that lost breed — many of today’s most popular dogs are walking tributes to breeds nobody kept alive.
1. Bullenbeisser
Also called the German Bulldog, the Bullenbeisser was bred for use in blood sports like bear- and bull-baiting, activities that have thankfully gone extinct right along with the dog. These dogs were compact and powerful, though quite a bit larger than their English Bulldog cousins. Their name translates roughly to “bull biter,” and they were known for their agility rather than sheer bulk.
Bullenbeissers were eventually crossbred out of existence, though they left one famous modern descendant: the Boxer. According to Hepper’s breed history, they shared many of the same characteristics seen today in the Spanish Bulldog and Dogo Argentino.
2. Cordoba Fighting Dog
The Cordoba was a crossbreed of several dogs — the Bull Terrier, English Mastiff, Boxer, and Bulldog. It exhibited a high tolerance for pain and a penchant for fighting to the death, a trait that ironically hastened its own extinction. Famed for its willingness to fight to the death, the breed died out in the mid-20th century.
The Cordoba Fighting Dog is considered one of the ancestors of the modern Dogo Argentino, a breed still recognizable today. According to Dogster, its muscular build closely resembled today’s Boxer and Bulldog.

3. Hare Indian Dog
The Hare Indian Dog was a slender, fox-like landrace kept by the Hare and other Dene peoples of what is now Canada’s Northwest Territories. Prized for speed and a keen nose, it was used to run down small game across the tundra rather than to fight or guard. As European dogs moved north and interbreeding became common, the distinct Hare Indian type disappeared as a separate landrace.
Some of the instincts that once made these dogs excellent hunters still surface in surprising ways among pet dogs today, including chasing behaviors like the ones explained in our piece on why dogs chase their tails.
4. Poi Dog
These short-haired, white dogs were fed poi, a starchy paste made from the taro plant, which gave the breed its name. Because dogs are carnivores that need meat to stay healthy, a diet centered on poi led to malnutrition and a variety of health problems. Combined with widespread crossbreeding, that poor diet eventually caused the original Poi Dog to disappear altogether.

5. English Water Spaniel
Last seen in the 1930s, the English Water Spaniel was described as a cross between a Poodle and a Collie, and was known to be an exceptionally good diver. The breed had a long literary history: Shakespeare referenced it in two separate plays, once calling the dogs a “water rug” in Macbeth.
Its curly, water-resistant coat stands in sharp contrast to the coats favored by many owners today; anyone shopping for a pet with easier grooming needs might prefer our roundup of low-shedding dog breeds.
6. Russian Tracker
Also known as the Russian Retriever, this huge dog measured about 30 inches at the shoulder and could weigh up to 100 pounds. The breed disappeared sometime in the 1800s, though the exact cause of its extinction is not known, according to Newsweek’s reporting on lost breeds. Its size alone suggests it was built for serious working duty rather than companionship.
7. Alpine Mastiff
The Alpine Mastiff is considered an ancestor of the St. Bernard and a younger relative of the Molossus. These mountain dogs were used to herd cattle, pull carts, and keep watch across the Western Alps for generations. Per Gudog’s breed history, it’s thought the breed became extinct in the 1800s due to extensive crossbreeding with other established dog breeds.
Its cattle-herding background places it firmly among working-dog history; readers interested in that lineage can explore our guide to herding dog breeds that carry the tradition forward.
8. Braque du Puy
This French hunting dog is thought to have taken its name from two brothers surnamed Dupuy, or Du Puy, who developed the type. The breed was never as popular as other French Braques and became extinct in the 1970s due to excessive cross-breeding, per Newsweek. Its extinction is notably recent compared with many other names on this list, a reminder that breed loss isn’t purely a historical phenomenon.
9. Talbot
The Talbot hound was the pure white predecessor of the modern beagle and coonhound. It was a slow but thorough scent hound, closely related to the bloodhound, and is thought to have been absorbed into that breed over time, according to the Rover blog. Medieval hunting parties valued the Talbot for stamina over speed, tracking scent for hours rather than sprinting after game.
10. Paisley Terrier
Also known as the Clydesdale Terrier, the Paisley Terrier was bred primarily as a pet and showdog version of the Skye Terrier, and it became the progenitor of today’s Yorkshire Terrier. In 1894, dog writer Rawdon Briggs Lee described the Paisley Terrier as “most suitable for a lady”, praising its silky coat and gentle temperament.
Its legacy lives on directly in today’s teacup dog breeds, several of which trace their delicate builds back to Paisley bloodlines. Full details on the breed’s history are documented on its Wikipedia entry and in Country Life’s survey of lost British dogs.
11. Kurī
Originally a Polynesian breed, the Kurī was later introduced to New Zealand, arriving around the 14th century, most likely from East Polynesia. Its coat varied between shades of yellow, brown, and grey, and it sported a bushy tail. Not everyone was charmed: French explorer Julien Marie Crozet wrote in 1771 that the dogs “were always treacherous and bit us frequently”, per Mental Floss.
European colonization devastated both the Māori people and the endemic dog breed alike, as imported European dogs overran Kurī populations and eventually replaced them entirely.
12. Salish Woolly Dog
Bred by the coastal Salish peoples of what is now Washington state and British Columbia, these thick-coated dogs were raised specifically for their fleece, which was sheared and spun into textiles. The arrival of Hudson Bay trade blankets, cheap sheep wool, and interbreeding with other dogs all contributed to the breed’s extinction, according to Rover.
Their dense double coats have no real modern equivalent, though owners drawn to plush fur today can browse our list of long-haired dog breeds for a living comparison.
13. Larzac Spaniel
In France, two breeds of pointing dogs — the Larzac Spaniel and the Braque Mirapoix — never made it out of southern France, according to research published by Project Upland. Regional pointing breeds like this one rarely gained national recognition, which left them vulnerable once local hunting traditions faded.
14. Braque Mirapoix
Paired historically with the Larzac Spaniel, the Braque Mirapoix was a pointing breed that, according to Project Upland’s research on lost hunting dogs, never spread beyond southern France before disappearing. Its story illustrates a common pattern among French regional gundogs: without a wider breeding population, even functional, well-liked types simply ran out of dogs.
Important Note: Detailed records for small regional breeds like the Larzac Spaniel, Braque Mirapoix, Hertha Pointer, and Llanidloes Setter are scarce. Much of what survives comes from a handful of 19th-century sporting writers, so some details remain uncertain.
15. Hertha Pointer
This pointing breed remained confined to Denmark for nearly a century until it finally died out, according to Project Upland. Like many single-country pointing breeds, it never developed the export market that helped similar Continental breeds survive into the modern era.
16. Llanidloes Setter (Old Welsh Setter)
In Wales, there was once a breed of setters known as the Llanidloes setter, sometimes referred to as the Old Welsh Setter. Writer Vero Shaw noted it was practically extinct by the late 1800s, lamenting that its loss was greatly to be regretted. Descriptions from the period point to a mostly white coat, occasionally marked with lemon patches around the head and ears.
17. Molossus
Grandfather of some of today’s biggest breeds — the mastiff, St. Bernard, Bernese mountain dog, Rottweiler, and Great Dane among them — the Molossus traces back to Greek antiquity. These dogs performed many jobs over the centuries, most particularly as guardians of people and livestock. Ancient writers, including Aristotle, described the breed as notably large for its era, and Roman and Greek households alike relied on it for protection.
18. Turnspit Dog
The turnspit dog was a short-legged, long-bodied dog bred to run on a wheel, called a turnspit or dog wheel, to turn meat as it cooked. It was also known as the Kitchen Dog, the Cooking Dog, or the Wheeling Dog, and full details of its working life are preserved on its Wikipedia page. The invention of the clock-jack, a mechanism that used heat from the chimney to turn the spit automatically, made the breed unnecessary, and by 1900 it was extinct, according to Extinction Cometh.
Key Insight: Not every animal called a “dog” is actually a canine. Prairie dogs, for instance, are rodents rather than members of the dog family — a naming quirk worth exploring in our guide to prairie dogs.
19. Dogo Cubano
A Cuban breed of mastiff originally used for bull-baiting, dog fighting, and recapturing runaway slaves, the Dogo Cubano is believed to have descended from Spanish Mastiffs introduced to the island, and it became extinct in the mid-20th century, per the Wikipedia list of extinct dog breeds. Its history sits alongside other Caribbean and Latin American working dogs, a broader story readers can follow in our guide to Mexican dog breeds.
20. St. John’s Water Dog
Originating in Newfoundland, the St. John’s Water Dog lived as a domestic worker and human companion, and it made an excellent companion for fishermen thanks to its love of swimming. Exported to England throughout the 20th century for crossbreeding, the breed’s numbers declined shortly after, and it went extinct in the 1980s. Severe restrictions and taxes on dog ownership in 19th-century Newfoundland had already sped its decline, and the last known pair, unfortunately, were both male, according to Dogster.
21. English White Terrier
The English White Terrier was bred from a white fox working terrier, according to A-Z Animals. Records on the breed are thin compared with more famous Victorian terriers, but its pale coat and compact build made it a recognizable presence in 19th-century show rings before it faded out.
22. Argentine Polar Dog
This long-haired breed was developed by the Argentine Army to act as sled dogs in the country’s Argentine Antarctic Program. The creation of the Antarctic Treaty System eventually forced Argentina to remove all of its dogs from the continent, since they were considered an exotic species there. The army then ended its breeding program, and the remaining dogs were moved to Patagonia, where most succumbed to disease after a lifetime in Antarctica had left them without natural immunity to common canine illnesses, per the Wikipedia list of extinct dog breeds.
23. Tesem
The Tesem was an ancient Egyptian hunting dog, frequently depicted on tomb walls and pottery as a lean, prick-eared sighthound accompanying pharaohs on the hunt. Researchers cataloguing lost breeds note uncertainty over its exact origins, sometimes listing its wild ancestor as an uncertain candidate such as Canis aureus, the golden jackal. Because the breed predates written pedigree records by thousands of years, most of what’s known comes from art rather than breeding logs.
24. Patagonian Dog
Little survives in the historical record about the Patagonian dog beyond its presumed wild ancestry. Researchers list its wild ancestor as the culpeo, or Lycalopex culpaeus, a South American fox-like canid still found across the Andes today. Like several other South American landraces on this list, it likely disappeared through a combination of crossbreeding and the spread of European dog stock into the region.
25. Original Irish Wolfhound
The massive hunting hounds described in medieval and early modern accounts of Ireland were reportedly taller and more heavily built than the show-ring Irish Wolfhound recognized today. As wolves became increasingly rare across Ireland, the original working wolfhound lost its primary purpose, and the breed’s numbers dwindled sharply over the following centuries.
Important Note: Documentation of the original Irish Wolfhound’s exact size, temperament, and decline is limited and often anecdotal, since formal breed records didn’t exist until long after the ancient type had already become rare.
The modern Irish Wolfhound was later reconstructed using surviving bloodlines and related breeds, a common pattern among today’s living rare breeds. Readers interested in how close some current dogs still run to extinction can browse our guide to the rarest dog breeds alive now.
Looking across all 25 of these extinct dog breeds, a clear pattern emerges: very few disappeared because they failed at their jobs. Most were crossbred into new forms, replaced by mechanization, or simply outcompeted by dogs better suited to changing human lifestyles. The Boxer, the Yorkshire Terrier, the St. Bernard, and the modern retriever families all carry pieces of dogs that no longer exist in their original form.
