The woods have eyes

Despite the fact that our dog is the most submissive creature in the world, she clearly has a keen sense of something (hearing, smell, dog aura?). She barked in the house late last night, which is very rare for her. We went out onto the deck to be greeted with this:

Despite the fact that there was next to no light coming from the house, it was plenty to reflect in the demon eyes of the beast - they just sat there staring at us. I went up to the stone wall to see it slinking off, not particularly bothered by my presence. Yellow eyes would probably mean coyote as compared to fox - it was certainly dog like in its movements.

*Ok, this is a Photoshoped picture - no way my camera was picking anything up in the dark, but it was just like that. Promise.
