Sad to say we have run into this same issue with our DD service dog. (1) You need to find out the reason for her not wanting the dog there, is it b/c of an allergy to dogs someone has?
(2) If not then you need to start out from the beginning with everyone understanding that your dog is now an extension of you, he is in fact 'your eyes'. If you don't stand your groud now there will always be an 'excuse' for them for you not to bring your SD. (3) if you have the support of your husband ask him to talk with them @ the situation. We always carried an short info page that we would had out to people who made comments, or smirks, we tried to educate them regarding SD. Maybe this is all the family needs, is an education of the way the SD benefits you, as your eyes. HTH LaQuita
