I believe you may be looking for Kanna37's short fic collection "It's A Dog's World". Specifically, the "True Measure" shorts contained therein. Chapter 17 "True Measure of a Man", 43 "True Measure of a Woman", and 52 "True Measure of a Heart" seem as if they might fit your memories of the fic you're looking for. The whole collection's very good, though! You can find it here:

Lady Goshawk,
Thank you so much. That’s the one.
