Blue fox breeding began in Finland in the 1920s. The bluish-grey variant of the arctic fox, blue fox is the most common fur animal farmed in Finland. Its coat has a very light tone in the winter, while it is rather dark grey in the summer.

Farmed blue foxes can also be partly or entirely white; depending on their genotype, these variants are called white or shadow foxes.

Farmed blue foxes descend from mated Alaska and Greenland blue foxes.
