The expression “man’s best friend” means “human’s best friend”, so it applies to both male and female.
Yes, I am aware of that.
It would have been more correct to say “this woman’s”.
Believe me, it was not an attempt to hoist the feminist placard. Truthfully, there are times I think it was a shame that women got the vote based on the voting choices of otherwise bright women. And there are times when I think that only property owners or taxpayers should vote.
