I've seen that adult Biewers photo before.. it's been along while since I've looked at Biewers to purchase but if I'm not mistaken.. it comes from a breeder in Hungary.. I'll see if I can find it somewhere but I know I've seen it..that background is difficult to forget. It always reminded me of the 60's...LOL
Those puppies look a bit odd to me to.. maybe it's the "chocolate" in them but really, most splitters
I've seen look just like little yorkie pups.. you really can't tell the difference especially at that age.
