OH GOSH NO it just might explain the white marking on the back (which Ive never seen before) you may want to ask the stud owner to check the daddys belly. If these kids have the speckles on their belly they carry the piebald gene. A Particolor yorkie is a piebald gene and they can produce mostly white and tan yorkies not the traditional black and tan, A pie bald gene carrier can mark a litter or has a very slight chance if bred to another piebald gene to produce a particolor. BUt breeding a true parti to a standard yorkie can produce a particolor and black and tan litter mix.
