Anyone else have a nervous pooper?

I know lots of dogs pee when they are nervous, scared, or excited. My little love...poops. With no warming. I have been trying to socializer her in public. I brought her to Petco (she pooped while I was holding her)...I brought her to a friends house (pooped while I was holding her)...groomer, she pooped before I even tried to hand her off. It doesnt matter if I take her out to potty before we leave, she still does it. And, she doesnt make a noise, wiggle or anything, its like its totally involuntary. I am working on it, got some pup diapers and think maybe the more comfortable she gets the less she will do it. But does anyone else have this stinky little issue
