“Fido,” one of the classic dog names, celebrates one of the classic traits of dogs: loyalty. “Fido” is derived from the Latin fidelis, meaning “faithful.”  According to dog legend, the original Fido lived in Italy from 1941-1958. A street dog adopted by a brick kiln worker and his wife, Fido followed his master to the bus stop every morning, and met him there every night. After his owner was killed in an Allied bombing raid, the story goes that Fido continued to go to the bus stop every night to wait for him for the next 14 years.
