A modern occupation

For a while, on my walk to work, I was behind this dog walker.

I know a few people who dog walk for a job and they love it. I wonder whether it’s a job that belongs only in cities? There’s one company who has a fleet of highly recognisable vans kitted out with dog cages and I really dislike seeing these vans parked up by a coffee shop or cafe, still full of dogs and some of them complaining quite loudly.
