I heard the white spot on her chest is a sign of a silky coat. 4 of my 5 puppies had white spots. I cannot find the white on any now. They are 7 months old now. I just stopped to flip them all, Quattro was in my lap and his entire chest is golden, but Robyn's is black. Their chest color seems to vary from one to the next. I had actually never noticed that before???
