Here at Crown Corgi we breed the 4 standard colors for our Pembroke Welsh Corgis. Black headed tri color, Sable & white, Red and white
(also fawn & white) & red headed tri Some will come with black cap means they just carry a black gene.
*Colors on the Pembroke's, yes they do change from time of birth.
Red tris are almost black tris when they are born, the older they get the more the red will come in.
Red and whites, are born very dark and become lighter red as they age.
Black tris stay the most the same. clown dots, black rim around ear.
Sable's change a lot also, pending genes.
