he isn't into things that are not scientifically proven. He has come around do some of them over the years because of research that has been brought to his attention. If anyone brings him actual research to say something works he will be all for it.
He definitely doesn't believe in chiro though. He has a bad back himself and has read a lot of research about chrio vs. non-chiro approaches to human back pain. The research he read doesn't support the use of chiro. (basically you heal in the same amount of time).
He is also against the whole "chiro fixes everything" attitude many places that do it (human and animal) have.
I did tell him a lot about my experiences with Touch therapy and chiro in the past for dogs. He was very accepting of the fact I saw real results. I didn't change his mind completely but, I think he did get a little more accepting of the possibilities.
He can be stuck in his ways at times but, hand him research supporting your views and he will read it and learn!
