My Baby goes to the supermarket, bank, stores and a few restaurants with me. It really depends upon the place. That particular restaurant is very dog friendly and he stays quietly on my lap or in his bag. I try to go to only restaurants that have outdoor seating. Hey if I have to sit with the cigarette smoke outside they can sit with my Baby who is much more pleasant
I bet if I had two of them, Ozzy would want to play though. If I feel he may be unwelcome I leave him at home or take my business to a dog friendly place. I guess it depends upon where you live and the individual establishments.
