The so-called "long-haired German Shepherd" is considered a "fault" in the German Shepherd Dog standard, according to the AKC. The long hair gene is recessive. Dogs with this coat look somewhat like the Tervueren type of Belgian Shepherd Dog. An example with pictures can be found here. Popular myth holds that long-haired German Shepherds ("fuzzies") are more affectionate, but there is little evidence for this.
