Masha exemplify the best qualities of 43 years of selective breeding under the purposeful planning of Debby Kay, author of the Labradors Breeders Handbook.
The intensity of black pigment on yellow Labradors is controlled by a separate gene independent of the fur colouring. Yellow Labradors usually have black noses, which may gradually turn pink with age (called "snow nose" or "winter nose"). This is due to a reduction in the enzyme tyrosinase which indirectly controls the production of melanin, a dark colouring. Tyrosinase is temperature dependent—hence light colouration can be seasonal, due to cold weather—and is less produced with increasing age two years old onwards. As a result, the nose colour of most yellow Labradors becomes a somewhat pink shade as they grow older.
If you're looking for a puppy, you'll find that Labs vary depending on what breeder you choose. Some Labs are bred for competitions testing their skill as working dogs, and others are bred to get as close as possible to the ideal look, movement, and temperament of the breed. You'll also find breeders who aim for both looks and utility. Labs bred for the show ring tend to be slightly heavier and more solidly built than those intended for canine careers.

As with some other breeds, the Conformation (typically "Show", "English" or "bench") and the Field (typically "Working" or "American") lines differ, although both lines are bred in both countries. In general, however, Conformation Labradors tend to be bred as medium-sized dogs, shorter and stockier with fuller faces and a slightly calmer nature than their Field counterparts, which are often bred as taller, lighter-framed dogs, with slightly less broad faces and a slightly longer nose. However, Field Labradors should still be proportional and fit within American Kennel Club standards. With Field Labradors, excessively long noses, thin heads, long legs, and lanky frames are not considered standard. These two types are informal and not codified or standardised; no distinction is made by the AKC or other kennel clubs, but the two types come from different breeding lines. Australian stock also exists; though not seen in the West, they are common in Asia. These dogs are also very good with children.
