The prairie fox is a genus of the carnivorous Canidae fox subfamily. It is a small fox about the size of a domestic cat and weighs about two or three kilograms. They are the smallest canines in North America. Prairie foxes are mainly distributed in foreign grasslands, such as Colorado and Montana. They are also found in the desert.

The prairie fox has large and pointed ears; black spots on the sides of the nose; the color of the body hair is light gray; the body and legs are orange; the tail color is black and the hair is relatively dense.

The prairie fox is distributed in the grasslands, dunes and deserts of North America and is the smallest wild canid in North America. Prairie foxes can often be seen in open grasslands or farmland. At present, the number of prairie foxes is not very large, there are still some in the United States, but the prairie fox in Canada has been completely extinct. Now Canada is preparing to introduce it again.

With the emphasis on environmental protection in recent years, the number has rebounded, but there are still less than 400. Canada's National Rehabilitation Program hopes to help boost the prairie fox population to more than 1000 by 2026.

Prairie foxes are omnivores, and their diet includes small animals, birds, reptiles, amphibians, fish, insects, and occasionally some berries and weeds.

The prairie fox is very agile and can reach speeds of 50 km/h while running. Even if the prairie fox has such a fast speed, it will encounter a formidable opponent. They usually hide in burrows to avoid the enemy. Prairie foxes are often out at night and mostly hide in burrows during the day. Depending on the seasons, foraging will also change. Prairie foxes are very cunning and run very fast, so they are generally able to escape danger.

The prairie fox breeds around 5 cubs at a time. It will live in a burrow for a month when it is just born, and it is still unable to perceive the environment for half a month after birth, so it needs the mother's feeding and protection. Cubs are weaned at seven weeks and remain with their parents until they reach adulthood. Prairie foxes are not very long-lived, generally 6 years old. At present, the artificial breeding of prairie foxes has been carried out. Under the artificial breeding technology, the physical quality of prairie foxes has been improved, so the life span of prairie foxes will also increase, and they can live to 14 years old.
