I'm hoping that the discussion about cryptozoology ends here, as it would lead nowhere sane.
But just as a few counterarguments: original belief of shape shifting into a werewolf did
not follow Hollywood design of a half-human half-wolf-kind-but-not-really-wolf monster. The belief was that a human actually became a wolf in every way, maybe just larger than normal wolves.
The second one is that if you prefer the Hollywood design, then
there is no such thing. Every monster-creating artist has had his/her own concept that largely follows that half-human half-wolf idea, but details are very different. There is no logic about which parts are from human and which ones are not. Mostly it has been defined by the budget and the level of technology. Before the tech allowed to create 100% CGI monsters, the looks of werewolves was limited by the budget for creating a werewolf costume and a mask to make a human actor look as something "scary with fangs". Obviously it's totally impossible to make a human look like a canine by giving him a costume and a mask, however sophisticated and expensive it would be. And this is where the non-wolf looking monstrous werewolf design is coming from.
At least some of the werewolf movies have been using real wolves or wolf-kind of dogs as werewolves and some newer ones have used CGI wolves (real-wolf-looking werewolves). I like that idea and concept the most. A human becomes a wolf. Completely, not partially.
You think that a werewolf should be a part human-part wolf and that the wolf part of a werewolf should be defined by what a werewolf would actually
need as a werewolf. The question in this case would be, why the fuck would she or he
need to look like a half-wolf in the first place? Why would it need
any of the wolf parts? A human can be way more dangerous and deadly than any wolf or werewolf and not only because no one would recognize the danger by just looking at him / her. And why should the "features" of a werewolf follow the logic of what a creature would need, when the natural evolution often doesn't seem to do so.
And maybe a werewolf would be able to have a litter of wolf puppies if she would stay in the werewolf form long enough?
I'm still trying not to be serious, just logical. I don't think that it's possible to have a serious conversation about cryptozoology without being at least somewhat insane.
