This was a great article! Thanks for posting.<p>I noticed a bit of this went I was visiting the ruins of Pompeii. Many stray dogs were waiting by the food court area but there were a few that followed us for the entire day. I'm not sure why they chose over everyone else but they did end up with some food.<p>It's possible that the strays that chose to follow us may not be allowed into the food court by the other dogs.
