What does a double dapple look like?


Not everything- is made for- chewing?

I was under the impression a double dapple looked like a piebald but with its "spots" dappled. But this dog on here swears she is not a double dapple (even though she has the common blindness problems particular to the pattern) but that she is a "piebald". Am I wrong??
