Bouvier Des Flandres Breeder Wanted

Hi there, I am interested in looking at a Bouvier Des Flandres for our family dog, one thing my son is allergic to dog hair and after some research this breed sounds perfect. I really like the information on their temperament but are they really one of the better "hypoallergenic dogs"? I look forward to your reply and if possible could we go and see the dogs. Kind regards Bronagh
