When you say do you have to dowel the '3rd tier', do you mean the 7" or the 5" (depending on if you count the dummy)?
I wouldn't dowel the 5" top tier unless you have a heavy topper going onto it but yes, I would dowel the 7". I wouldn't dowel the dummy either but make sure that you have a firm board under the 9" :-)
AI agree with snowflakebunny23 dowel every cake that has another cake resting on it! Except the dummy cake and only dowel the top tier if there is a cake topper. And congrats on doing your first wedding cake.
