Wolves or Dogs? Tracks in the Zagori

No, this is not a metaphor for the current aggressive state of the Greek election campaign.

Can anyone tell me about these paw-prints, relatively fresh tracks in the mud around some rainwater puddles on a path in a lonely, thickly wooded area frequented by wolves as well as by shepherds' dogs- and possibly by domesticated dogs from a nearby village (though I have never seen them here)?

Do they belong to dogs or wolves? I am curious to know. Perhaps someone discovered the DNA of a Molossian war-hound?
