This is the response from the Illinois Department of Natural Resources to your question. The Illinois Dangerous Animals Act prohibits ownership or possession of wolves except for zoological parks, federally licensed exhibits, circuses, scientific or educational institutions, research laboratories, veterinary hospitals or animal refuges where they must be in an escape-proof enclosure. "There is no separate designation for the crossbred wolf/dog or coyote/dog mix, and as such are accepted as wolves if they are represented as wolf crossbreeds." "It is no defense to a violation of Section 2 that the person violating such section has attempted to domesticate the dangerous animal." Illinois Revised Statutes, Chapter 8, paragraph 242(2).
