When it comes to conceiving of the character Ermentrude Wolfenbarger, it’s primarily based on the odd fact that wolves were actually this associated with witchcraft in some countries like Switzerland before (she is Swiss herself). Mind you even their domesticated relatives dogs were also highly associated with witchcraft in countries like France, Germany and Britain at some point, the association still exists in some African countries like Cameroon and Ghana even not all Africans believe in this themselves. Though there are African sermons and devotionals that do bring this up, they also bring out other topics like forgiveness and arrogance for instance. It is one interest but not the only one around, as they also discuss other matters like love as well.
But even then this is one association that does deserve some reappearance, if one wants a break from the usual stereotype, more often than not it’s informed by a very limited experience with certain things and peoples. Very limited interest in such things and peoples as well to boot, that’s why a number of fictions tend to be kind of dyed in the wool repetitive. TV Tropes might be interesting but not to a reliable extent since most of its obsessions relate to modern pop culture or mass culture in some way or another, not so much earlier folk cultures and high cultures alike. For both of these two, you might as well peruse both older documents (including those dating back to the early modern period) and academia to better delve into such subject matters that don’t appear often in modern mass culture.
And if you want to go the extra mile, then you could also peruse inspirational literatures and journalistic literatures on the same as well, but in a way that makes one wonder if American mass culture/pop culture is kind of very selective in some fashion. Maybe not necessarily selective but more in the lines of being really detached from the past, if because American culture kind of came out of the blue when compared to not only Europe but also China, India, Iran and arguably Senegal, Ghana (when it was both the Ashanti Empire and the Gold Coast), Mali and the Democratic Republic of Congo. From the early modern European standpoint, associating dogs with witchcraft’s rather unsurprising, which goes to show you how common this association was in the past.
It’s not at all forgotten in African countries, if because it’s still relevant to this day. But I feel European countries have gotten more postmodern, alongside the profound American influence that came by. Germany had a vexing attitude to dogs before and still does to this day, only in the past it had a lot to do with witchcraft. At present it’s due to both canine predation and people poisoning dogs out of spite, but either way Germany seems more apprehensive around dogs than America is. The same goes for both Austria and Switzerland, since they also have the same problems as well. It’s kind of befitting that one of the most prominent dogs in Germanophone culture is the demonic familiar of Dr Faust, as popularised by Johann von Goethe.
One that’s more deeply embodied in German culture than what Cujo does for American culture, in some regards a lot moreso. And then there’s Malleus Maleficarum, which brings up the association of wolves with witchcraft. So associating either wolves or dogs with witchcraft in the European mind wasn’t that strange before because it used to be this commonplace, similar associations exist in America as a country but only in isolated pockets among some indigenous communities. This is where the American attitude to dogs diverges from its German counterpart, one that seems more consistently enthusiastic around them. That’s not to say Germans don’t value dogs at all, but it’s undermined by recurring suspicions of foul play. Something America doesn’t have to the same extent, really.
The association of wolves and dogs with witchcraft wasn’t really that strange in early modern Europe, owing to its previous ubiquity, that had a character like Ermentrude Wolfenbarger emerged in say 1618, she wouldn’t have been surprising. She is a witch who not only habitually uses dogs and wolves to attack people, but also bewitches them the same, sends dog spirits to torment them and turns into a wolf herself, a witch who’s right at home in African Pentecostal thought as she would be in early modern European Christian thought. But given Canada’s greater proximity to America that a character like Ermentrude Wolfenbarger would stick out like a sore thumb, as Canada was also formed fairly recently and very much a settler-colony as America is.
On the subject of serial killers and pet dogs, there are instances where such characters do like and care for dogs. Most notably the likes of Harold Shipman (who had a black poodle), Myra Hindley who had a dog named Puppet and Dennis Nilsen who had a dog named Bleep, though the thought of murderers having dogs wasn’t so odd during the witch trials. But that’s got to do with them being associated with or suspected of witchcraft in some way that it was to be expected, Ermentrude Wolfenbarger being a murderous witch who likes dogs is pretty unremarkable in this light and likewise the same would go for Harold Shipman, Dennis Nilsen and Myra Hindley in a way. In modern fiction, the closest equivalent would be Dudley and his dog Muttley, which speaks to a kind of underrepresentation.
As underrepresented as witches with dogs, which are historically interconnected and interrelated in Europe before. To the point where if American fiction is in short supply of villainous dog owners that the only viable alternatives are real life stories of murderous dog owners and folklore involving witches who have dogs for familiars, especially if these beliefs are outside of mainstream American culture (Europe at some point, Africa at present). Ermentrude Wolfenbarger and her dogs would be a return to the earlier portrayal, as found in Johann von Goethe’s Faust, so is her using their wild relatives the wolves to do the exact same thing.
These were even mentioned in the book Demons of Urban Reform, which features mentions of documents encountering similar characters in real life at the time. Ermentrude Wolfenbarger and her canine association might be a controversially refreshing change of pace, a villainous witch who uses both dogs and wolves to antagonise people and animals alike.
