During the Migration Period and later Hungarian conquest of the Carpathian Basin, numerous nomadic or semi-nomadic tribes moved into the area that is now Hungary.

The Magyars probably brought sheep and dogs with them, and established a pastoral culture in the Hungarian plains.

[6] After the war, it was revealed that fewer than thirty Kuvasz were left in Hungary and some sources indicate the number may have been as few as twelve.

[7] However, as a result of this near extinction, the genetic pool available to breeders was severely restricted and there is conjecture that some may have used other breeds, such as the Great Pyrenees, to continue their programs.

[1] Although generally a healthy and robust breed which can be expected to live approximately 12–14 years, the Kuvasz is prone to developmental bone problems.
