Another thing to keep in mind with the domestication of wolves, it's thought that the only way to even have the slightest chance of being able to effectively raise a wolf from infancy, you would have to take them before they open their eyes, according to researchers.

I highly doubt (assuming this would even work with Grimm) that you could get your hands on a Grimm infant that young anyways.
