This was actually a pretty big Disney deal - Lady was one of the first female Disney characters to have conceivably had sex when she had her wild night out with Tramp. When she returned home, Jock and Trusty immediately offered to marry her so her reputation wouldn’t be sullied by her outing.
You go, Lady. Get your freak on :)
