I asked something like this also a while ago, I wondered that also, if all the pups have the same color coat as pups but the coat could lighten up dramatically, then how would you know what to mark early on? ...Should you wait til their about 1 yr old?...What if the parents are quite different in color, couldn't it go either way for the pup? ...Or possibly could they take after a Grand Parents color? ....Curious also
