Throughout history, many dog breeds have faced the threat of extinction due to factors like war, disease, changes in breeding practices, and a shift in societal needs. While some breeds managed to bounce back through dedicated efforts, others were lost to time.
This article is for general knowledge only and is based on information from online sources.
1. Irish Water Spaniel

Known for their distinctive rat-like tails and dense, liver-colored curls, Irish Water Spaniels nearly vanished in the 1800s. As hunting practices evolved and fewer sportsmen needed specialized waterfowl retrievers, these intelligent dogs faced a dramatic population decline.
Today, only about 200 puppies are registered annually worldwide. Their water-repellent coats and webbed feet make them exceptional swimmers, though many people have never seen one in person.
2. Tibetan Mastiff

These massive guardians once protected Tibetan monasteries from predators and thieves. When China invaded Tibet in 1950, countless Tibetan Mastiffs were killed, pushing this ancient breed toward extinction.
Their thick double coats evolved for the harsh mountain climate, allowing them to survive temperatures as low as -40°F. A handful of these dogs were smuggled out of Tibet, forming the foundation for today’s recovering population.
3. Otterhound

With fewer than 800 Otterhounds remaining worldwide, these shaggy water dogs are rarer than giant pandas! Their near-extinction began when otter hunting was banned in England in 1978, eliminating their primary purpose.
Sporting rough, waterproof double coats and webbed feet, these boisterous hunters can swim for hours. Despite their excellent noses (second only to Bloodhounds), few people choose them as companions today.
4. Dandie Dinmont Terrier

First mentioned in Sir Walter Scott’s 1815 novel “Guy Mannering,” these distinctive terriers with “topknot” hairdos face extinction with fewer than 100 puppies registered annually. Originally bred to hunt otters and badgers, their popularity plummeted when these activities declined.
Their unmistakable appearance includes a rounded head with silky hair and a long, low body. Despite their small size, these dogs possess remarkable courage and an independent spirit that once made them favorites of celebrities like Queen Victoria.
5. Skye Terrier

After the famous Greyfriars Bobby, a Skye Terrier who guarded his owner’s grave for 14 years, died in 1872, the breed enjoyed brief popularity. Ironically, this loyal breed now registers fewer than 30 puppies annually in the UK.
Their distinctive features include a long, low body covered by a straight coat that parts down the back and hangs like a curtain on both sides. The Skye’s dramatic decline occurred as working terriers fell out of fashion.
6. Chinook

In 1965, only 125 Chinooks existed worldwide, with the Guinness Book of World Records naming them the rarest dog breed. Created by polar explorer Arthur Walden in New Hampshire, these sled dogs nearly disappeared after his death.
Their golden-tawny coats and friendly temperaments make them stand out from other northern breeds. A dedicated preservation program saved them from extinction, though they remain uncommon today with their patient, eager-to-please nature making them excellent family companions.
7. Lagotto Romagnolo

After World War II, these curly-coated Italian water dogs nearly disappeared when marshlands were drained and waterfowl hunting declined. Their salvation came from an unexpected source: truffles.
Farmers discovered their exceptional scenting abilities made them perfect for finding the expensive fungi. With wooly, waterproof coats that resemble sheep more than dogs, these resourceful canines have rebounded from near-extinction.
Their naturally keen noses can detect truffles growing up to three feet underground!
8. Azawakh

Civil wars and droughts across West Africa’s Sahel region nearly wiped out these elegant sighthounds in their native lands. Traditionally kept by nomadic Tuareg people, these dogs are built for survival in one of Earth’s harshest environments.
With their visible bone structure and deep chest, Azawakhs can reach speeds of 40 mph despite minimal body fat. The first specimens didn’t reach North America until the 1980s, and they remain extremely rare outside West Africa.
9. Stabyhoun

With only about 7,000 worldwide, this Dutch farm dog’s name means “stand by me” in Frisian dialect, perfectly capturing their devoted nature. After World War II, agricultural mechanization nearly rendered them extinct as fewer farms needed versatile working dogs.
Black and white spotted coats give them a distinctive appearance, while their ability to hunt, retrieve, and control vermin made them invaluable to Dutch farmers. A dedicated breeding program in the Netherlands saved this national treasure from disappearing completely.
