The first impression I had was that it was a fox. I am in va. If coy-wolfs are here, that would make sense.
My concern is that the deer got ambushed, and that my kid and wife's dogs play in the same area. It happened soooo fast, there wasn't even time to grab and point my camera which was right in front of me on the desk (pic included of camera on desk). Even if I had a gun (and I would buy one just for this task- I mention the 30-06 in jest a friend has one available), there was no way for me to get a line on him without blowing out my sun room windows. I could only wish for a field shot like the OP. There was no realist way for me to get him, and that concerns me.
