HI,
Just wondering why a dominate choc breeding would produce light noses on pups? Will they darken as they mature? In case your wondering there's neither sire or dam carry yellow.

How old are the pups?

Nose color in chocolates doesn't have anything to do with whether they carry yellow:

Very informative article!

Sometime they look more pink at a few days old. They do darken, just like the pink goes black on a yellow. Would depend on how young you are talking. Have never seen a light nose on any chocolates other than babies.
