They have 7 actual wolves, and 1 wolf-dog hybrid. The 8 animals are divided into 3 groups in different enclosures. They talked about how the hybrid was a rescue (and they don't support breeding wolf-dog hybrids).
They also said a couple of their actual wolves were arctic wolves, but I have a suspicion that the 7 actual wolves are all generic gray wolves, and are not of a pure subspecies.
They don't have any other animals or canids, but they did talk a lot about coyotes, like about the differences between wolves and coyotes and about human-coyote conflict. There was also a taxidermy wolverine in the visitor center.
