But this is not the point, the point is to know if the line is clean or not (blaming X or Y is another topic) and how to proceed for checks. In addition, mixing could occured without the breeder noticed it, when the french breeder visited Edit's kennel some years ago, she noticed there was a (male red colored) Saarloos there and had some concern about it.

Furthermore, those red puppies are only one of the "anomalies" we have in the line, I guess you saw some other pics Margo put. With the huge number of offsprings of this line, the impact in the breed as a whole is really important and should be investigated as best as possible the sooner possible.
