It is thus a particularly good herding dog, and an excellent guard without being fierce. There is a marked difference in appearance between the sexes. Wide between the ears, and a somewhat domed skull. The stop is clearly defined, but should not be too pronounced. Cheeks are flat.
Muzzle is rather short, tapering evenly toward the nose seen both from the side and front above.
The nostrils are well developed. The colder of the lips and muzzle shall be black except on chocolate brown and light fawn dogs where brown is permitted. The eyes shall be of medium size and almond shaped. The color shall be dark, but may be lighter according to the color of the dog. Yellow is not acceptable.
