Can't tell you a weight - just wanted to tell you first to ignore whomever said that, too many people these days have no idea what a dog of normal weight looks like as so many are overweight if not obese.
I go by my dogs' condition rather than the weight itself - I only weigh them when I have gotten them to ideal adult weight, so that I have a point of reference in case of illness.
If I can feel the ribs down the side and bottom, but not at the top either side of the spine, then I consider them to be the right weight.
If she is at the right weight, then tell the next person that she is ideal and well fed, and if they persist tell them where to go!
