Dogs are allowed on the underground. The Underground goes to Heathrow Airport… but dogs are NOT allowed in the airport. We’d been to meet people before, and left Timothy at home, but (and not just when he was getting old) we liked to take him with us as much as we could: because HE loved to go with us whenever he could.
So we took him on the Underground to Heathrow one day. It was before his “dog in a bag” days, but we had already by then snuck him into a couple of places in a bag. He didn’t have a specific bag at the time, just whichever bag we had available that was about the right size for him.
While at Heathrow, I kept him in a bag of course, hiding him on the other side of my legs whenever we were near anyone. A BA-uniformed lady approached us beside a glass balcony wall somewhere by a lift or escalator. We thought we were in trouble… but no! It was the charm of Timothy: she stopped us to ask if she could take a photo because she loved what she saw!
We floated around the airport after that. He went back to Heathrow a couple of times after that, the same way, too. Whenever he got to go somewhere like that – where there are lots of people and no other dogs, he’d always make the most of it: twisting and turning his head to see everything and to make sure he took it all in. He never tried to get out – I’m sure because he knew that the bag was the safest, and only, way to stay there.
