The old standby of figuring a puppy's weight is to double his/her 12 week weight. Doubling of the 13 week weight might give you a more accurate estimate. The heritage of the Biewer Terrier has dogs of all sizes, so remember a large or tiny dog back several generations may show up in the size of a puppy once it is full grown.
