You recall correctly...they are extreme piebald.
White dogs with several spots of color are usually piebald, but can be extreme piebald if the spots are few and small. A white dog with markings only on the head is extreme piebald.
In the breeding of white, full color is dominant over piebald. Piebald is dominant over extreme piebald. If your dog has a piebald parent, he's carrying piebald. If he has an extreme piebald parent, he's carrying extreme piebald. If both parents are full colored, it's still possible that he might be carrying either piebald or extreme piebald if there's a piebald or extreme piebald somewhere in his pedigree.
