It's a hyena people. I've seen hyenas in real life in the wild, they don't have to be spotted. The one's I saw were that dark reddish color.
Of course she did, Chrissy, didn't you know that hyenas are native to Maryland? I mean, it's soooooo obvious.....
I think it's a fox with mange. Mange seems to be really out there this year, my mom's dog has it, and she's never running free by herself. It's very contaigeous, the vet said all she had to do was walk where a fox had been to catch it. http://www.terrierman.com/mange.htm
I dunno, it looks too big to be a fox. I suppose it could be some sort of mutt with mange though, that would explain it's peaceful nature... not the grazing though. For now I'm sticking with the warg theory
