Well I agree it is a wolf. But as for dogs breeding other critters I shot a coyote out from under a australian sheperd once. We had a whole pack of coy-dogs running around here and they were causing all kinds of trouble for area farmers. Happy to say after 2 weeks of coyote hunting the problem was solved. We killed 7 of them and some were very weirdly marked. One was even spotted like a Australian sheperd.
