How about an old, starving and mangy CoyWolf.
Is your link to the great PBS story re CoyWolfs?
Or eastern coyote...cross between a wolf and coyote. We have been seeing lots of them where I live near Pittsburgh. Greentree PA even has a warning about them on their community webpage.
Some of my co-workers ridiculed me after I told them about them. I have seen them for years.
When Greentree posted the warning I was vindicated.
