We're all allergic to cats here !!??!!
Lived with them for years, and bred them too

But as time went on, we reacted more and more to their fur. Both OH and DS have asthma. DS was wheezy and gets eczema from their fur/dander/saliva on their coat. OH was ok unless they got on his shoulders (Burmese like to be CLOSE!) and all of us could have ripped out our own eyes if we got a fine hair from them in our eye. Nothing seemed to stop the swelling, itching and pain.
So as they got older we didn't replace. The last one died about 6 or so years ago.
OH has been diagnosed
officially as allergic to DOGS! However, he tested this regularly at dog shows and didn't react at all! (He was also told he wasn't allergic to wheat, yet reacts really badly if he eats it, go figure.

personally, I felt the skin test at the hospital was a joke)
None of us react to the Bedlingtons. I can even be around them when they're wet. Most dogs make me gag when they're wet.
Really, the only way to know if a dog will be ok to live with an allergic person, is to have proper contact with them first ;-)
