Wedding for a male dog and a female rat in chinese zodiac signs

I have two good friends, who will be married in two weeks. I want to give them som advise for their wedding and marriage based on their chinese zodiac signs, which are dog for the male and rat for the female.
Can someone help me with an advise on their relationsship and marriage, aswell as the implications of getting married in the year of the woodsnake?
Thank you!
