very interesting more so as I have two rather large dogs that thankfully have not started to attack me yet. Did you see the report on TV where the wife of a PD sufferer also said that she had noticed that her husbands odour had changed my first thoughts were that he had changed his after shave lotion without telling her! but turns out he had'nt so maybe there is something in it?
certainly worth further investigation anything that could speed up the diagnosis of PD has to be good my personal experience meant that I was diagnosed with burn out syndrome and stuffed with anti depressants for over a year before my GP referred me for tests to see what was going on and they discovered my PD.
mans best friend to the rescue :-))
