What Are DudleyYellow Labradors?
Posted March 25, 2009on:
Pigmentation in Labs mostly occurs in yellow Labradors. Recessive genes cause pigmentation. Pigmentation in yellow Labradors normally shows up in the tail, feet, lips, nose, gums, and around the periphery of the eyes. The color of the pigmentation is usually black or liver. With age the yellow Labradors nose may turn pink.
The liver pigmentation is called Dudley. If the dog is a lighter yellow the nose color will be lighter and a yellow tending to a reddish shade will have a darker Dudley look. In the majority of yellow Labradors the black nose fades around two years of age.
