Jan-Baptist Jansen purchased a yellow rough haired male, Vos, in the area of Boom, Belgium. Vos, born in 1885, became the foundation sire for the Laekenois and Malinois varieties of the Belgian Shepherd Dogs, and can also be found in the extended pedigrees of several Dutch Shepherds and early Bouviers, in the Raad van Beheer’s NHSB studbooks.|
Vos (later designated Vos I) was mated to a brown/brindle shorthaired female known as Lieske, or Lise de Laeken. From this mating came Diane and Mouche, (short hairs who played important roles in the development of the Malinois), Tom de Vilvorde, a grey rough hair, and Spits, also presumed a rough hair. Spits was bred back to Vos to produce Moor, a black rough hair who is also apparently one of the first recessive blacks in the history of the Belgian Shepherd Dogs. Moor, bred back to her grandsire, Vos, produced Poets, a light fawn rough haired Laekenois female who did well in several exhibitions at the end of the 19th Century....
