I don't take my furbabies shopping but they have been on vacation. They have rode in the care on weekend trips and long hauls to see other potential puppies. They have never thrown up or acted nervous they love it. However, once at a truck stop the poochon that I was taking care of long term got very nervous at all the sounds and people. I get a hoot at my darlings they do get quite nasty when someone comes near the car when they are together but apart they will let somone near them. I do not let just anyone pet my furbabies friends and relatives.
