The standard calls for markings that are "clear and well defined" This is also meant as well for the markings on the face and muzzle. Mahogany colour is always preferred but we most often see varying shades of ft. Head and muzzle should not be adulterated with black hairs (sometimes called "smudgy" or "sooty") They should also be of good proportions, meaning the area of mask should not exceed further than the cheek. as in fig 10. Often we see the muzzle almost completely black with a tinge of colour peeking through. This is a fault and should not be dismissed when choosing breeding partners.
Problems with Head and Muzzle markings: 1. Markings too light. straw in colour2. No markings at all.3. Sooty or smudgy, adulterated with black.4. Markings too large on muzzle and cheeks5. Hairs on chin and muzzle "fuzzy" or "beard like"(this is not a colour problem but a coat problem)
