Yellow Labradors known as "Dudley’s" can have pink noses, and the same colour around the rims of the eyes. Their colour can appear as light flesh on a light yellow to brown on a red or dark yellow.
Unfortunately, current breeding standards do not permit Dudley’s, which are extremely rare, entering dog shows. Also breeding yellow Labs to correct pigment abnormalities is not dependable.
Yellow Labradors can also be affected by genetic combinations for colour.
Some appear as dark yellow with black pigment. There is black around the muzzle and eye rims, but the nose will become pink as the Lab ages.
