When you want to go invisible:

1. You climb under the tiniest footstool in the house;
2. You keep your tail tucked under your backside and avoid wagging it;
3. You put on an innocent, but sheepish face;
4. You pretend the legs and tail sticking out from under the stool have nothing to do with you.

Visual guidelines:

This dog has performed the invisibility manoeuvre. The causes are still under investigation – I am checking all my slippers for bite marks and whether my bed has been slept in by uninvited guests. The local cat population is being examined for missing tails and ears. Husband will inspect his flowerbeds for signs of tunnelling. Meantime, Dog remains invisible.
