The White Shepherd is a direct descendant of the German Shepherd Dog and the two breeds share common roots and are similar in appearance. However, the White Shepherd evolved from a continuous selection for a working companion dog with that exclusive color, beauty and elegance as seen both standing and in motion. His high degree of intelligence and sense of loyalty have allowed him to become one of the most versatile working dogs serving mankind(Wikipedia)
The breed has a distinct personality marked by direct and fearless, but not hostile, expression. The ideal dog is self-confident and maintains a certain aloofness. It is eager and alert when needed, willing to serve in its capacity as a companion, guard, guide dog, herding dog, or whatever the circumstances may demand. The dog must be approachable, quietly standing its ground and showing confidence and willingness to meet overtures without itself making them. Lack of confidence under any surroundings is not typical of good character. Any dog that exhibits unprovoked aggression and attempts to bite any person, dog or other animal must be disqualified and removed from any dog show event.(Wikipedia)
