The photo on the left depicts a champion black and tan
Pembroke Welsh Corgi male who has white markings on the top of his muzzle, chest,
around his neck as a narrow collar, on his legs and underparts. This is commonly
referred to as a tricolor. The black encompasses his eyes which makes
him what is called a black headed tricolor. The photo on the right is
of another champion male that shows the typical markings found on a black headed
tricolor. Please note that it is perfectly acceptable to have a Pembroke Welsh
Corgi that is black and tan with no white, but a Pembroke Welsh Corgi that is
black and white with no tan present is a mismark. The tan is often not present
at birth, but appears within a few weeks after birth.
