Hello.  I have two cardigan corgis.  I do not have pembrokes.  I did recently attend a Pembroke akc finals and I believe the Noble Heart corgis were representing that day.  I know the RINCON Corgi breeder Kathy Dolge she lives in Carpenteria CA.  I will look through the information I collected that day and see if I can find a little more information.  on their website looks like they have quite a few dogs in their group.
