oh yes! people are so ignorant when it comes to that. if they can't see anything physically wrong with you - they ask or assume you are "training" the dog. Fortunately the trainer who trained my pit bull also gave me a slew of lines to tell people. Him, being from NYC, most were sarcasticly humorous but the lines he gave me to combat that aspect work. "yes, i am training it." "it's for seizures", "it's for me and really not any of your business" because if you tell them it's for anxiety or PTSD they want to get into a whole conversation of what it does for you and how it helps. and you will always have the people that want to pet it. i always refuse. even though my pit is the sweetest of the sweet - she is working, not some amusement for passer by's. and they do (the dogs) know the difference when the vest is on - it's work time. when it's off it's play time...But main thing like my trainer told me - do and say what you are comfortable with there is no law that says you have to disclose what it is for, it has a license, a vest, and you are in control of the dog. sounds rude - but it's for a disablity that we have and part of that disablity is not dealing well with people and places out side out "safe spot".
