What is the significance of dogs in birthdays?

This is a folk saying in a version of the Book of Life in the Third World, which means that all people born in JOE (1994) have the basic features of imitating the Chinese zodiac, namely the core monument of life, the zodiac. That is, like dogs, they are loyal, steady, honest and frank, so some versions are also called "crazy straight dogs", which is the instinctive feature of the folk zodiac.
