The Dogs of Pompeii

After the bus left our group at the entrance of the ghost city, buried by years of solitude and emptiness, we started our walk through the steep, stone streets. And to my surprise, I noticed that we were followed by a pack of stray dogs at a certain distance, six or seven of them! The y escorted us throughout the tour and then left us again at the entrance where we started, following another group of tourists...

I wonder if these dogs were descendants of the ones referred to in a ?welcome mat?of one of the Pompeii homes that warned cava canem, ?beware of the dog.? Who knows...
