You can tell by the photo of the animal that it is not a purebred wolf, but a hybrid.
Yes, indeed it is easy to tell that this is a hybrid!

This man should not be allowed to handle these animals if he is a lazy, ignorant jerk off who can't identify a yorkie from a mastiff (okay, maybe a little over-exaggerating there). He really needs to be relieved of his position, and I hope that this poor animal gets the proper treatment he deserves.
