Fair enough, I would too, I wasn't criticising! I was just lucky enough to know I was allergic from a very early age so I've never been in that situation.

Some people do get animals they know they're allergic to in the hope that they'll 'adapt', trust me, I've spent a lot of time trying to dissuade them!

As you say it is an autoimmune condition where the immune system is attacking things it should ignore, the immune response being flem etc. If the OP's immune system ignores everything apart from dog hair then the only solution is to cut down the dog hair. But if they are alergic to other things, like wheat, then their immune system is attacking that as well as the dog hair and therefore the dog hair appears to be the sole culprit when it really is just the over flow.

That was my understanding of the BBC's Bang goes the theory programme on it - where one of the presenters who suffered from alergies ate a pig parasite.

Hey whatever works for you, but it has no basis in anything resembling current medical knowledge so I don't want other people to read it and think 'Hey if I give up wheat I can get a GSD!'

If you're genuinely interested in finding out how allergies work go to the library, there are lots of biology and physiology books that are suitable for lay people, you have completely the wrong idea at the moment, sorry!

I would say the opposite. That it was not worth NOT trying giving up toxins which your body may well be alergic to also - if that reduces your effect from the dog alergy. I guess you have worked out that I think that a lot of doctors are some of the most close minded people on the planet!
