Pieds can have no ringer white, but there is a specific Pied pattern that makes a Pied a pied and not a ringer.


I don't have any photos at this time to show you the difference, but basically, a Ringer is an animal with a regular pattern but a white patch or splotch.

Pieds have a distinctive pattern that goes with the white that they have as well.

Hopefully someone else can share with you those distinctions, or you can check out this link. Jon does a good job of explaining it
