Allow me, the intellectual of my family, to share the knowledge...

Most people think that dogs wag their tails only when they're happy.
But it's a little MORE-- complicated than that.

Wagging is a form of communication for us, we don't usually wag our tails when we're alone (siao arh, think we are as silly as humans who talk to themselves?).

It's one of the only few methods used to show our emotional states. The wag can convey good spirits, fear, aggravation, dominance, or submission. It doesn't mean that when we are wagging our tails, we are happy-campers! We could be in fear... and may need to pounce on you to defend ourselves? It all depends on the situations, our moods and if we are friends.

But one's thing clear... we are always so happy when we see our Ma and Pa.
I wuff them so much!
No instructions needed, just shake our butts and tails off!! Let me get Ma to video us when we do the booty dance soon!
