the main differences between the dutch shepherd and the german shepherd is that a large dutch is about 65 pounds. a large gsd is 85-90 pounds (strider is 95 and acceptable for shows). also the dutch shepherd is brindle, a color that hasnt been found in the purebred gsd for quite some time. they are not very different. they do come in long and short and wire-haired coats (also one I dont see on that site, long curly coat). they were mostly created through crossings of german shepherd with the belgian shepherds (malinois, groenedael, tervuren, laekenois). the wire haired (wolf hound looking type) coat came from the laekenois. the most common is the smooth coat. Ive only worked with one of these dogs, was a firecracker in protection, agility, and obedience. and I just might have to import one for myself someday soon.
they are bit more energetic than a gsd, and though anything is possible, I wouldnt recommend them to a beginner. any of you know how the malinois compares to the gsd? dutchs energy/drives are more similar to the malinois.
