Any advice for this couple?

Hi, I am Year of the DOG and my finace' is Year of the Ox. According to this website, we are "well suited." We do have our ups and downs and different personalities; however, it seems that we also have a lot in common, have the same sense of humor, same fears, etc and we often meet in the middle. We have been together for 3.5 years. There is a little bit of an age difference, with me (the female) being older. Does this even matter when it comes to Chinese Horoscope or Signs?? Just wondering if you have any general advice for a DOG/OX relationship?? Thank You!
