This is very interesting, Stephanie. Thanks for all the trouble of sharing the instructions and videos. I like the way you think! It was fun to watch the different scenarios.
The instructions about how to tell what they like makes sense when I relate it to how Buddy reacts to food and other items. We just offered him Duck yesterday. He'd never had it before and he had a "keen interest" and clearly considered it something he needed!
It was interesting to see Roddy with the various items. He looked a little surprised with the water - at least to me - kinda like "Whassup with that?" The cooking oil is used in a dog food recipe of Dr. Pitcairn's because it has essential fatty acids (vitamin F) so maybe that's why he like it?
You're smart to realize that you make a difference in their reaction to the therapy. There have been numerous studies on the effectiveness of placebos with people based on what the doctor said when he gave it to them. If he/she thought it was going to help, might help, etc. The doctor may or may not even know it is a placebo, if it's a double blind test. Over and over, the doctor's belief effected the effectiveness of the placebo. There's really no reason that doesn't also apply to non-placebo medications as well, and opens up the whole discussion on energy based medicine and how there are many things we can't quantize or isolate, but yet have very definite and predictable influence on our health and well being. Too many things are discounted by "modern medicine" because they don't fit into their paradigm and way of testing. Chiropractic and acupuncture are two examples of treatment modalities that have suffered much ridicule in the past - and still do in some circles, despite their effectiveness.
The pictures show a lot of improvement in the rash. That's really encouraging to see. And without the side effects that cortisone type ointments would have.
Very cool posting - thanks for sharing!
