Cesar Millan recommends using a consistent non-mark (the tsch sound) when a dog is misbehaving. If the dog continues to misbehave, it is important to follow-up the non-mark with some action (e.g. a body block or time-out) so that the dog understands that there are consequences for ignoring a non-mark.
