The top of the skull should be broad between the ears giving the impression of masculinity and power. Correct male heads have a "character" to them, usually expressed in the form of sharp masculine angles. They may even have a certain coarseness to them yet not so coarse as to look like a Mastiff or Bulldog, conversely the feminine head may have slightly softer angles. There should be depth in the muscle mass, which lies on top of the skull. The top skull must also have a slight arch from stop to occipital ridge (Arrow 2) and from ear to ear (Arrow 1). The skull is 60% of the length from tip of nose to occipital ridge.The stop should be well pronounced in the male head. The zygomatic arch (Arrow 3) is also strong, giving structural support to the upper jawbone and lower portion of eye.
Not typical head type problems: 1: Too much dome for the top skull, should not look like the apple type skull of the Cocker Spaniel2: Too coarse "Bull dog" or Mastiff like3: Too fine or feminine, lacking in masculinity, conversely bitches should not look like dogs4. Disproportionate head, too small for body size, conversely too large for body size
