Dire wolves have made their appearance on Game of Thrones since season 1, episode 1. According to the books, dire wolves are as large as a small horse.
Danielle Dufault, the host of Animalogic, explains a few things about dire wolves. For one, they’re very real and exist, but they’re not as big as the books describe.
A dire wolf is about 25% bigger than a gray wolf and about 70% carnivore. Scientists estimate its jaw had a powerful bite — about 1,900 pounds per square inch, but it’s debatable because their bite would be more forceful than a hippo’s bite.
Dire wolves somewhat exist today. The National American Alsatian Breeders Association’s developed the dire wolf project since 1987. They selectively breed dogs to bring back the look of the prehistoric animal. An interest fact Dufault makes, the dire wolf was extinct around the same time humans started to domestic dogs.

Dire wolves lived in North and South America up until 10,000 years ago when they went extinct. Having survived 1.79 million years, their extinction is still somewhat of a mystery. One theory is that since dire wolves were 25% bigger than gray wolves, that they were that much slower.
