The skull is flat, unwrinkled, and fairly long. Viewed from above, the skull tapers slightly from the occiput to the muzzle. Cheeks are flat and clean. The bridge of the muzzle is flat and parallel to the line of the topskull. Viewed from above, the muzzle actually tapers slightly from stop to nose, but appears rectangular and nearly as broad as the skull, due in part to the thick whiskers on the muzzle.
Lips are tight and darkly pigmented.
The hair on the muzzle is long and thick, forming the characteristic beard. The Miniature Schnauzer has a complete set of large, evenly spaced, white teeth meeting in a scissors bite. Nose is black and of good size. Eyes are small, oval in shape, and dark brown in color. They are set wide apart and deeply under the brow.
