Breeder estimate was about 6lbs. Mother's around 5lbs while the father's about 3.5lbs. My girl's a little leggier and longer than her mom but about the same proportionately as her brother though he was a little shorter/smaller than her at the time of choosing and they were both still visually a bit smaller/shorter than their mother.
