The way I see it, a malinois is just a tan dutch shepherd and a dutch shepherd is just a brindle malinois.
Answer by Happy Go Lucky Mastiffs
in the 1800’s there wasn’t as much to distinguish between the Belgian Malinois, German Shepherd and Dutch Shepherds as there is today. They were all considered shepherd dogs and while they were different breeds, they were also cross-bred with each other on occasions. Some of the early German Shepherd dogs were brindle in color and after a few years into this breeds development the brindle color was taken out of the gene pool.
It wasn’t until the 1890’s that these three breeds went their separate ways and became breeds of their own right, and hence, the Dutch Shepherd became the brindle Short Coat shepherd dog. The Belgium Shepherd Became the long coat variety. And the same with The Belgian Malinois Became the short coat German shepherd we have today Hope this helps.
