Dudley Labradors are uniquely marked dogs that stand out with their lack of pigmentation in certain areas such as the nose, eye rims, and feet. Unlike the typical black or yellow Labradors with dark noses, Dudley Labs have pink noses from birth to old age. The debate continues as to whether Labradors with reduced nose pigmentation should also be classified as Dudley Labs, but the key difference lies in their genetics. Labrador puppies are born with pink noses that may darken to different shades, depending on the density and type of melanin in their cells. The color of the nose is determined by the genes inherited from the parents, with ‘Bee’ genes controlling black or chocolate color and ‘Eee’ genes controlling yellow coloration. When these genes are combined in certain ways, they can influence the pigmentation of the nose.
Yellow Labradors can have noses of various colors, including pink, brown, and black. In order to be yellow, a Labrador must have one of three gene combinations: eeBB, eeBb, or eebb. The ‘ee’ genes determine the yellow coat, while the ‘B’ genes influence the shade of the nose, which is affected by melanin levels. Labradors with eeBB or eeBb genes will have black noses and eye rims due to a higher density of melanin, while those with eebb genes will have brown or lighter noses. DNA testing can determine if an adult Labrador carries the genes to produce Dudley puppies, as lack of pigmentation in yellow Labs is considered a fault in the show ring.

As Labrador retrievers age, it is common for their once black noses to fade to a pink hue. This natural process, called depigmentation, is normal and nothing to worry about. The enzyme tyrosinase, responsible for producing nose pigment, becomes less effective with age, leading to the pink nose phenomenon in senior Labs. Interestingly, the pinkening of the nose may be less noticeable in warmer weather, as the enzyme functions better in heat, a condition known as ‘snow nose’. While most pink noses in Labs are harmless and due to aging, it’s essential to keep an eye out for any changes that may indicate a medical issue. In cases where a Lab injures her nose, resulting in a pink scar, rest assured that it will likely revert to its original color over time.
What to Expect with Dudley Lab Puppies? Dudley Labradors may have lighter noses compared to their dark-nosed counterparts, but they are just as lovable and loyal. When considering getting a Dudley Lab puppy, keep in mind that their low pigmentation can make them more susceptible to sunburn. It’s important to protect them from UV rays, especially in sunny climates. Consulting with your vet can help you come up with a plan to prevent any sunburn incidents. In dog shows, yellow Labradors with pale noses, eye rims, and feet may receive lower scores. However, if you’re looking for a loving family pet or a dedicated working dog, a Dudley Labrador can be just as amazing as any other Labrador Retriever. They make great companions and hard workers, regardless of their pigment.
