Regards all things dogs at airports.
Last year @ LHR T3 I saw a pooch in a Louis Vuitton holdall/dog carry case going through security, only for it to appear again in the Gallaries lounge still in said bag. Sat perfectly happily on a chair, and I was half expecting the pooch to have some gold plated bowl with champagne in it. Didn't see it on our flight to PRG mind.
I had to google the bag and it is indeed a legit LV product priced at approx. £300. You can guess what the owner was like - can't remember if flights to Nice were still from T3 at that time
The whole process was barking - sorry couldn't resisit.
