The most important one is missing:

Fass!

You better know what it means when a dog owner points at you and says "Fass!".

There is a hilarious episode by German comedian Gerhard Polt about this word where he plays the owner of a Kampfhund (the genuine grandson of the great-uncle of the dog of Adolf Hitler) who goofs around alternating between "Fass!" and "Nicht Fass!" not realizing that the dog is not capable of distinguishing between the two.
