Our yellow lab with black eye rims and pink nose is now eight years old. I thought her nose would darken as she clearly carries the black pigment allele visible in her eye rims, but it didn't. Is she still a Dudley if she has black eye rims - I always assumed the nose would match the eye rims and they don't match. If she has any pigment in her nose it is light brown. Is this common?
An unpigmented nose in a dog is a 'Dudley nose' - there's some debate online as to whether or not a Dudley lab is just a dog with a pink nose, or a dog with a pink nose and pink eye rims, or if they must have unpigmented paws to count as well. There is no reason a yellow labrador could not have black eyes with a pink nose. Yellow color can be present whether the skin is pigmented black, liver, or unpigmented. It sounds like your dog's skin pigment is black, but the nose is an area where it is unpigmented. What color are her paw pads?
Hi Fay Fife! Traditionally Labs referred to as Dudley Labs don't have pigment in their eye rims or paws. You can see lots of photos of Dudley Labs in this article - https://www.thelabradorsite.com/dudley-lab/ You might like to compare your dog with those pictured
