On a side note ,I have a psychologist buddy who has his own therapy dog , he sometimes brings it to help patients deal with issues difficult issues , one comment he gets alot "when I saw you where a dog guy ,and it was healthy and happy , I figured you new something about keeping us alive " obviously I am not divulging anything anybody could identify , but you have to think all the walls a happy healthy dog can tear down by rolling over and saying rub my belly ,please"

I definately hear you on allergy issues and such , but that's part of patient selection ,intentional exposure vs accidental . I know locally you can't go near a medical office wearing perfume or cologne of any kind, and I had a partner for 11 1/2 years and never got discriminated against but I always had I'D and vet papers etc.. proving my partner was safe and certified .
