Broken teeth resulting from field work are not to be penalized. The nose is large and solid black. In profile, the nose is on the same line as the top of the muzzle and extends just slightly beyond the forepart of the muzzle. The eyes are relatively small and oval in shape with an alert, sometimes fiery expression. Dark brown eyes are strongly preferred.
Lighter eyes are less desirable and the lighter the eye, the more serious the fault.
Eye rims are dark. The ears are strongly erect, of medium size, triangular in shape, and set at the outer edge of the skull, but not too low. The ears are slightly rounded at the tips and wide at the base. When the dog is alert, a vertical line drawn upward from the dog's cheek will run along the outer edge of the ear. The ears are extremely mobile and react sensitively to sounds.
