Hi Patti
It is hard to tell this for sure because I just saw the Pink & White didn't find it's exact place in the dominance order list

Otherwise I would say it must have been the hidden of your DAD.
But since it isn't sure if maybe Pink & White is dominant over the Red & White it might need deeper pedigree investigation to figure this out.
Maybe you can attach a screenshot of the online pedigree?
