I WAS WONDERING WHAT IS A PIEHEAD, WE HAVE A FEMALE PUP AND SHE IS WHITE FROM HER HEAD DOWN HALF WAY TO HER BACK. CAN SOMEONE PLEASE HELP ME UNDERSTAND THAT.

never heard the expression, but I would think it just means that she's mismarked - not a problem unless you bought her for showing. OES should have a white head, neck & forequarters, but white patches on the body are not desirable.
HTH

Heard of Hare Pied or Pied Hare but not Piehead. do you think you may have misheard or the person speaking to you was not that knowledgable?
