The Dudley Lab - An Unusual Labrador Retriever

October 16, 2014 – 05:59 pm

A Dudley Lab is a Labrador retriever that lacks pigmentation on the eyes, eye rims, muzzle, and nose. This is a genetic trait that is very rare and affects only the yellow Labrador retrievers.

This trait can't be considered as an abnormality of the genes.

Usually yellow Labs have black pigmentation on those areas while Dudley Labs don't.

The distinct yellows of Labrador retrievers

The coats of Labrador dogs have two distinct yellows. They differ in the genetic combination of colour or what is called as genotypes.

If a yellow Labrador retriever has a bloodline of one or two genes that are programmed for a black hue, then that dog will most likely have black pigments that can vary in intensity.

On the other hand, those yellow Labs which have a lineage of genes that are encoded for chocolate colours then most likely that dog will have a chocolate or liver pigment which is also known as Dudley.

These labs vary in colour, such as light flesh, light yellow, dark yellow, dark brown and even red.

These combinations depend on the breeding and on the parents' colour.

Take for instance, two Labs bred together. There is a tendency that the offspring is a combination of both liver-pigmented yellow and black pigmented yellow.

Yellow Labs with pinkish nose

Some Labs have pinkish nose, which is commonly referred to some people as snow nose or winter nose. Many of the yellow Labs have dark noses during the summers and would just eventually fade during the winters. This cycle is not totally understood and can been seen in other northern breeds such as Malamutes and Huskies.

To determine if it is just a snow nose or if it is really a Dudley Lab, all you have to do is to check the gum tissue and the eye rims, which should also lack the pigmentation.

Typically this kind of Labrador retriever will also have tan or light pink skin while other Labs have black pigments in these areas. Additionally, a true Dudley has the tendency to sunburn easily, so they should not be exposed too much to the sunlight.

The pigment on the nose of yellow Labs can vary. Some yellow Labs have slight black pigment around the muzzle and eyes. Some have pigmented nose that begins to fade as puppies (usually around 2 years of age) and will eventually become black again until they are 8 years old and above.

Gulp. Red faced. Um, uh, well no I don't

I loved having my Yorkie Jessica on my lap with her head at the open window when I was driving cross country! It actually helped me stay focused. 3500 miles is a loooooong way to drive alone! So messing with the dogs kinda kept me awake. She was more on my left leg than lap, as she is tiny and had to stand to put her nose at the window!
I know, I know, I KNOW!!!
I don't make a habit of it, does that help any??
But what the heck happened to freedom of choice? Darwinian Natural Selection? Why do we have to legislate everything? For crying out loud
