There is no such thing as a Marwari Mule. This is a Pega donkey, a breed from Brazil often used to create gaited mules (using Brazilian gaited horse breeds). -- by the way, Jumentos e Muares means Donkey's and Mules.it's not a photographers name.
When the owner found her mare, the horse was protecting a newborn fawn from several foxes trying to eat it. The injured mother deer was nearby. The mare protected both until the mother was well enough to move on.
