Could be a myth, I never talked to a biologist only DEC officer and they are not biologists. What I think we have around here is wolves. I saw plenty of track and plenty of really big canines that were no dogs or standard large coyotes. Maybe as Gnu states Brush wolf. however that article says that canine was tested by the Texas biologists as a mix breed. I would have like to seen it .. I wasn't there, that is an API article
