I'm also interested in an example (if you have one) of desensitization that would be faster than flooding under the same circumstances
I'm not sure that desensitization would ever be faster than flooding. I simply meant that desensitization can occur very quickly, depending on what you're working on, and depending on the dog. :-) At least I don't think I made the claim that it would be faster, as I do think that flooding, if it works, will result in quicker change yes. An example of a situation in which desensitization can be used quickly - I know somebody who, when they introduced their dog to a clicker, the dog freaked. Whale eye, ears back, ran out of the room in fear. Because the noise was so sudden (and likely close to the dog's ears, as they do have such sensitive hearing), the dog was initially fearful of it. Simply repeating loud clicks (which would be flooding) was not working, so they used a desensitization process in which they put layers of tape on the clicker to muffle the sound, until the sound was not scary to the dog. With each click they removed one layer of tape, each time, watching the dog's reaction. The sound got ever so slightly louder each click, but it was so gradual, so that by the end of just one session (a matter of minutes) the clicker was being used at full strength and the dog was fine forever after. It's an example of desensitization being used that works very quickly. Gaci's desensitization to cars driving by (and not chasing) only took three-four days, and she never looked back. That is very quick by desensitization means.
I'm sure the fear is ever present, and the dog is aware of the stimulus (sometimes, if it is in view), but the point I was trying to get at is that the dog can be aware of the stimulus,. even see it, and not be in fear of it. Once you finish a step in the process, at the end of it the dog is not only "not bothered" but the dog is looking for more. So you give the dog more, and move to the next step, and see how the dog reacts. You learn to gauge a dog's level of fear by its behaviour, and when one lives with an inherently fearful dog you learn to really be able to understand their signals, as an individual dog (Gaci and Shimmer will display different signs to know when they are uncomfortable, yet both of their issues are fear-based). If Gaci is working with me, tail up (stump), observing her surroundings but not staring, ears forward, with her normal happy expression, I know she's not in fear. If she is staring/focused, tense, freezing - those are extreme signs, I know we've gone too far. If she is panting, looking at something then back at me, showin some white eye, has flitting attention (from me to environement, back to me then back to environment), and has trouble responding to me adequately (for things that she knows very well), then she is not over threshold yet but is uncomfortable, and she is doing her best to communicate that to me. Of course there are many ranges in between, there aren't three concrete "levels", so I am always cognizant of what she is doing an how she is reacting in different situations. For purposes of desensitization, even though she might know the stimulus is there, the goal is to always keep her in the "happy" range, and not the "intermediate" or "over threshold" range. So she might see the stimulus, and of course she knows that if it comes closer it becomes fearful, but at that distance it provides no fear for her, so you work on lessening the distance in a manner in which the stimulus never actually becomes fear-illiciting. That's the core of desensitization.
Now, I'm not saying there may never be a place for flooding, there may be, and I'm not saying I would never ever do it (although I lean more to that end than the other) but because it's a crapshoot no matter how "rightly" it's done, it's a very risky procedure to do, which is why I opt for the one with a better track record. It can work well for some dogs, and it can go horribly wrong, there is no way of knowing until it's too late unfortunately. So when working with an already messed up dog, the last thing I would want to risk is a dog that is more messed up, and who has lost its trust in me.
We do have to use the terms carefully here to keep the proper meaning of the word, as they are both specific procedures that are effortfully performed, in an attempt to change a behaviour. So a thunderstorm is not a flooding procedure as you have no control over it. In order for it to be flooding, you would have to have the dog in the thunder until it stops reacting (whether the dog stops being fearful or it becomes helpless is determined by the dog, or whether the dog still remains fearful and the fear just doesn't go away, or it may sensitize), and only end the thunder (or fireworks) when the dog has stopped reacting, and then repeat again in the future. Because you don't control them, they can't be considered true flooding procedures, even if the dog is apparently being "flooded" with the stimulus, which it very well may be. But in order for it to be used as a behaviour modification tool as classically defined, it has to have a beginning and end that is controlled by the human.
