Wolfdogs (“wolf hybrid" is not a term that is accurate or used in the WD community anymore, since it’s been scientifically proven in 1993 that dogs are a subspecies of wolf, therefore the offspring of their mating cannot be called a "hybrid" since a hybrid is the result of crossbreeding two different species together, which is not the case in this scenario) are not vicious, wild or aggressive animals that kill humans.
In fact, on the same population of animals, dogs attacks/murders come in a bigger percentage than wolfdog attacks/murders on humans.
Just like with any animal, whether it’s a parrot, lizard, dog, cat, fox or cougar, there can be attacks. However, exotic animals prefer fleeing rather than fighting if they feel threatened, while it’s been proven that more domesticated animals, such as dogs, have much higher chances of fighting rather than fleeing due to the fact that they aren’t that skittish of human strangers anymore. I’ve read cases of dogs just jumping out of their backyard and attacking a random passerby, but never heard of an exotic animal do that. I own a Husky dog, so I like dogs, in case some of you may be wondering why I’m saying this. I’m just stating facts, that’s it. Exotic animals such as wolfdogs and foxes are more skittish than dogs when exposed to new environments, they’ll feel unsure and will rather try to distance themselves from what causes their insecurity.
When there’s an exotic animal attack, regardless of why the attack occurred (more than 90% of exotic animal attacks seen on Animal Planet or TV Shows are cases when the owner was irresponsible and had no idea how to take care of its special needs exotic animal), the medias go crazy about it for 2 reasons: 1) they’re against exotic animal ownership and want to brain wash everyone by constantly talking about the attack for weeks or months, hoping it will dissuade some from owning them and 2) owning a tiger or other carnivorous exotic mammal, for example, is not common, so when one of these animals attacks someone, the media wants to have the best bits of the story to get more views on their show/newspapers, and so will continuously talk about it, making it look horrible and saying the animal is aggressive and will turn on you. Not!
In my province (Quebec) there are over 500 dog attacks every day. If the medias were to talk about each attack, they’d lose the public’s interest. Honestly, who wants to hear about “dog attack”, “dog bit passerby”, etc. everyday? Not me, at least. So when they have the opportunity to talk about someone impressive that does not occur everyday, they amplify the story and make it sound “incredible”.
Back to your question, neither wolfdogs or foxes are “aggressive and wild animals that will try to attack you or others for no reason”. They can attack but it’s either due to 1) they’re hurt, stuck their paw in a crate, etc. and you try to untangle them and they bite, as a response to being in pain, 2) they’re protecting their favourite toy/food or 3) someone is acting aggressively towards them, they try to flee but have no place to go, they’re cornered by the person, so in response, they’ll attack, out of fear and self-defense. Never, never have I heard of a responsible exotic carnivorous mammal owner being bitten by its animal. I’ve only been bitten by my foxes 4-5 times in all my time with them and it was for the following reasons: Miko hurt his tail, I tried to check what was wrong and he bit me, and the other times it was food/toy possession-related.
Here’s a scientific study with 13 bottle-raised wolves and 13 domestic dogs put in several situations (aggressive passerby, indifferent passerby and friendly passerby) whose purpose was to study the reaction of each of the animals.
5/13 dogs growled/tried to attack when the experimental passerby acted aggressively, while none of the wolves did.
