Story about white: When I asked my grandfather - why you prefer white dogs? Replay was: During nights, when wolfs attack herd shepherd is to recongize and differ dogs (fiting with wulfs) and wulfs - to shut wolf from rifle . And if dogs are white this is much easy to do. Take into account that sheeps in Georgia are only white - shepherds thought, that ships with black spots can "call harm" to herd...

Another story about white: When I asked serviceman of famous Soviet kennel "Krasnaja Zvezda-Red Star" why they have not white Nagazis? Replay was: There is a few personnel in kennel and they can not provide appropriate clinning for white ones. So whites always look "dirty"...
