Animals have conditioned reactions. These conditioned reactions can last for years (just like people).
Animals react to our feelings. If you react to the animal's feelings they, in turn, will react to us. This can happen with "positive" feelings also. With creative reaction we are intentionally choosing our "feeling". In the case of TT it's a peaceful feeling (ie not happy, sad, mad, glad). With TT we are saying "right now you can be peaceful".

There are NO "bad" animals. Often humans judgements are so far off of what's really going on with the animal. In addition to physical senses being stronger than humans, animals can pick up on our feelings. TT is therefore about healing, not correction. We must be peaceful and calm ourselves (as humans) in order to truly resolve an unwanted behavior in animals.
