Jordan, you're correct. The problem is though, is that a lot of BYBs have bred double dapples into their pie lines which is causing each piebald with the DDs in their' background to throw blind and/or deaf puppies. Most of the pups, by looking at them, you'd never know they had dapple anywhere in their line. Some will have a few very faint patches that are barely noticeable but most will just be the regular bicolour or tricolour that a pie should be, or they'll be born completely white. I hope that makes sense.
