For a long time, mostly until the 1970s, humans feared wolves despite them not being our natural predators. Not only do wolves act aggressively in the presence of humans – nowadays believed to be a reaction out of stress – but during periods of scarcity, these canids find it much easier to attack animals reared by humans as they are less capable of fighting back. This is especially common in Eurasia, where many wild wolves’ diets are made up of domesticated animals.

As a result, wolves have been persecuted regularly, becoming extinct in certain countries, like Japan, Scotland, and England. In Japan, wolves used to attack horses, and those infected by rabies would even attack humans, leading to the announcement of bounties for killing them. This would even become national policy in the Meiji Era, ultimately leading to the complete extermination of any native wolves in the country. Similar bounties were established throughout the United Kingdom, as wolves were quite a nuisance in places like Scotland, where they were known to dig up corpses from graves. Eventually, the combination of hunting for bounties and sport and deforestation caused by agricultural expansion led to the wolf being wiped out throughout the United Kingdom.

However, not all wolves that went extinct can be traced back to human activity. Some, like the Newfoundland Wolf, went extinct due to a lack of specific prey, while others, like the Cave Wolf, couldn’t adapt to the colder temperatures caused by the Ice Age.

List of Wolves That Went Extinct

Wolf	Characteristics	Where Did It Live?	When Did It Go Extinct?	Reason for Extinction
Bernard’s Wolf (Canis lupus bernardi)	1. White fur with black tips 2. Social, like other gray wolves	The Arctic Archipelago, specifically	Between 1918-1952	The exact reason is unclear, but most likely reasons include a limited range combined with occasional hunting by humans
Cascade Mountains Wolf (Canis lupus fuscus)	1. Cinnamon-colored fur 2. Approximately 5 ft long & weighed 79-108 lbs	Pacific Northwest (British Columbia, Oregon, and Washington)	Around 1940	Exterminated by European settlers
Cave Wolf (Canis lupus spelaeus)	1. Smaller legs compared to the rest of their bodies 2. Closely related to the domestic dog	Europe	Late Pleistocene (between 129,000 and 11,700 years ago)	Inability to adapt to the drop in temperature caused by the Last Glacial Maximum
Dire Wolf (Aenocyon dirus)	1. Despite being referred to as a wolf, as well as possessing similar proportions to the Yukon and Northwestern wolves, the Dire Wolf is not a wolf  2. Hunted and fed on large prey like bison, camels, ground sloths, etc.	Eastern Asia and the Americas	Early Holocene (between 125,000 and 9,500 years ago)	Changes in temperatures caused its main prey to die out, and it was unable to compete with other carnivores when it came to hunting smaller prey
Hokkaido Wolf (Canis lupus hattai)	1. One of two wolves native to Japan 2. Light gray fur with dark guard hair along its back	Hokkaido, Japan	Around 1889, possibly even earlier	Extermination by local farmers in the Meiji Restoration period, with the help of strychnine-laced baits
Japanese Wolf (Canis lupus hodophilax)	1. Smaller compared to the Hokkaido Wolf 2. Feral domestic dogs are often confused for this wolf due to the close similarities	Japan (Honshū, Shikoku and Kyūshū)	Around 1905	Combination of persecution as a result of Meiji Era policies and the introduction of viral diseases like canine distemper and rabies
Late Pleistocene Wolf (Canis lupus)	1. Varied coat color 2. Preyed upon the megafauna of the time like bison, mammoths, and musk oxen	Throughout the Northern Hemisphere	Late Pleistocene (between 129,000 and 11,700 years ago)	Unclear, but potentially because of the loss of prey and habitat with changing environment
Newfoundland Wolf (Canis lupus beothucus)	1. Mostly possessed white fur, but some could change fur color seasonally 2. Hunted the Newfoundland Caribou 3. Closely related to the Labrador Wolf, despite the ranges of the two sub-species not overlapping	Newfoundland, Canada	Around 1911	Population decline of its primary food source – the Newfoundland Caribou, which almost halved over a decade from 120,000 to 6,000

Also, it is worth noting that the Mexican Wolf (Canis lupus baileyi) is very likely to become extinct in the wild, with only 200 individuals recorded living in the Mexican wilderness. Breeding programs are currently taking care of around 380 Mexican Wolves in captivity, but whether or not they will ever be released into the wild remains uncertain.
