It turns out that the image of the kind-hearted society lady with a doggie was known at least as far back as the fourteenth century. Chaucer's prologue to The Canterbury Tales:
'In curteisie was set ful muchel hir lest.
Hir over-lippe wyped she so clene
That in hir coppe ther was no ferthyng sene
Of grece, whan she dronken hadde hir draughte.
Ful semely after hir mete she raughte
But, for to speken of hire conscience,
She was so charitable and so pitous
She wolde wepe, if that she saugh a mous
Kaught in a trappe, if it were deed or bledde.
Of smale houndes hadde she that she fedde
With rosted flessh, or milk and wastel-breed.
But soore wepte she if oon of hem were deed,
Or if men smoot it with a yerde smerte;
And al was conscience and tendre herte'.
