Yes, Biewers are pure Yorkies not mixed with any other breed! The only difference is that the white coloring was kept and nurtured. Piebald yorkies have always been occuring in the breed but years ago breeders would "cull" these puppies because, heaven forbid, someone should find out that their dogs produced such "odd" colors. Mr. & Mrs. Biewer in Germany saw the beauty in this varation and decided to further the breeding and develope it into a healty and lovely dog. Yes, they do have specific markings as Snowyorkies, Sue, mentioned. Those definitely have to be there for them to be a true Biewer. I have a male and he is 13 months old and he's in the 8-9 lb range, but he's got a lovely structure to his body, solid, so I'm not too worried about his weight, the health is there. I think that there is still a lot of variation in their weight, and they are a little larger than our Yorkies here in the states. I'm sure that in years to come the breeders here will probably get their weight down to the Yorkies, but I personally would love to see them stay the way they are...
