Good question - made me smile when I think of mine. I have to two waggers (Carly and Max), one waver (Kirby) and two wigglebutts (Molly and Muffin).

You'd think the two dachshunds would be the same (Max and Muffin), but they have totally different personalities too. Muffin's little behind just shimmies when she gets happy - her tail wags her butt. It's so cute.
