Funnily enough I once took my Groenendael to the doctors with me, as it wasn't for something where I would expect to be examined, didn't occur to me that there might be a problem, but that was when I only had the one dog.
As I don't drive I pretty well take my dogs everywhere they re not expressly banned.
In the covered shopping precinct in Kingsw3ood near me I have the shop staff come out to make a fuss of the girls when I tie them to the roof supports while I buy my fruit and Veg or nip into Halifax. Have taken both the fosters into Halifax as I didn't want someone petting them without me being there (in both instances I could watch the dogs while in the shop).
As a result they are very chilled out, well mannered, and I have even gotten all three on the bus at once when I bought heavier stuff than I wanted to carry all the way home.
Being just medium size (20 inch at the shoulder) and not rush hour I could shove two under the seat and one sat close by the side of the seat so as not to obstruct other passengers.
