Ditto Carn Euny village:

"Go late in the afternoon and see if the black and white sheep dog greets you and gives you the guided tour. It was very obliging when I was there with the family and went out of it's way to point out the fogou, before retiring to a discreet distance, all the while keeping an eye out to make sure we didn't cause trouble, then escorted us back to the car park."

Not a scary dog thankfully, it was a canny old Border Collie. I'd love to think it was still there doing the guide routine.
