You know what? You're right. I should probably add the meaning to my blog post. The Dog represents honesty and loyalty. Babies born during this year are believed to have these characteristics. Also, it shows their compatibility with other animals. So a person born in the year of the dog will be most compatible with people born in the year of the rabbit, tiger and horse, whereas they will be least compatible with people born in the year of the dragon, ox and goat.
This website goes into more detail about this zodiac. I was born in the year of the horse! (Dec. 1990)
