Well, yes and no... I think. Here&apos;s how I came up with my theory.

Keeping in mind that all creatures of the Grimm world are those based on animals and stories, you&apos;d have to look for a "grimm" story. What comes up is the grimm and simmilarly, the black shuck. Both are recorded to be large, black (what color is Nick&apos;s hair? What color has all the Grimms we&apos;ve seen so far wear all the time? think about it...), spectral dogs with flaming eyes (flaming eyes as in nothing but hell red. No sclera (whites), no pupils, just red). The difference? "Grimms" are recorded as violent killing machines that roam the country side at night. "Black Shucks" are kind dogs that gaurd graveyards, churches, and travellers. My theory is that the humans (who grimms help and protect) recorded Nick&apos;s species as Shucks and the Wesen (who grimms hunt and slaughter) recorded them as Grimms, though they are one and the same. I think what happens with Nick is that he gets the whole flameing eyes thing when he sees Wessen but can turn into the all out spectral dog once he learns how. This also contributes to the reason why Grimms aren&apos;t considered Wesen. Unlike wesen, who can go half man-half beast, full human, or full beast Grimms can only be in human form or beast form.
