Saarloos Wolfhonds eyes

Question
Can a Saarloos Wolfhond have one brown eye and one blue eye?

Answer
I had never heard of one of these dogs before, so I cracked out my rare breed dog book. According to my book, the eyes should be a yellow color. Is your dog a purebred Saarloos? or a mix of one?  Do you live in the U.S?  I would be interested to know where you got him from.  It is common for huskies and malamutes to have a blue and a brown eye. Could it be possible that he has some in him?
