In late eighteenth-century Mexico City, Spanish colonials, particularly members of the urban middle and popular classes, performed a number of weddings and baptisms on puppies (which were wearing clothes or bejewelled collars) in the context of fandangos or dance parties. These ceremonies were not radical challenges to orthodoxy or conservative reactions in the face of significant economic, political, religious and cultural Bourbon reforms emanating from Spain. Employing Inquisitorial investigations of these ceremonies, this article explores the rise of pet keeping, the meanings of early modern laughter and the implications of the cultural and religious components of the Enlightenment-inspired Bourbon reforms in late colonial Mexico.
