one thing to let u guys know, the chinese zodiac is based on the chinese calender year, with the chinese new year starting some time between late january to early febuary, the date of the acutal new year varies every year between those times. so if u are born in early to mid january, you belong to the sign of the previous year.
for example if u r born in early to mid january, 1982, you are acutally a rooster not a dog
and if you are born late january to early febuary, there is good chance that u belong to the sign of the previous year, really depends the new year's date on that year.
