I am not brave enough, and Paddington isn't quite small enough (a little over 4 lbs) to sneak into places. He usually pops his head out of his purses, so it makes it kind of hard. I do, however, put him in his purse when I am at the apartment that my boyfriend and I share. Our Landlord lives on the property (actually right above us

), and the last time he saw me and Paddington he wasn't very happy. We paid a pet deposit, but that was for a cat that we don't have anymore... we aren't sure if we're allowed to have dogs lol.
Anyway, he sits in his purse when we walk from the car to the apartment, and one time I met my neighbor on the elevator. When we got to our doors he asked where my dog was, I told him in my purse... he had no idea, and the dog was right next to him the whole time! What is funny is that this particular one has mesh on the sides so that the dog can look out, and you can see right through it. People just don't expect to see a dog, so they don't notice it!
