Dogs in Ancient Greece and Rome

I came across fascinating information about dogs in Ancient Greece and Rome in Encylopaedia Romana. I hope you will find it as fascinating as we did at Babette and friends.

"There on the left as one entered...was a huge dog with a chain round its neck. It was painted on the wall and over it, in big capitals, was written: Beware of the Dog."

Petronius, Satyricon (XXIX)
