Being a dog walker is one of those jobs I will always envy. You get to meet loads of cute animals and you get your steps in? It's the ideal combination. I know that it's probably a lot more complicated than that, and you probably have to deal with all kinds of unpredictable behavior. Still, I've got to appreciate those who secure the bag solely through their love of animals.
It also makes me kind of sad that many people see walking the dog as a chore. Sure, many of us are busy and can't always give them the exercise they need with our schedules, and being torn away from the couch to trot them around in the rain isn't the most fun. However, it's kind of a fundamental part of the whole dog ownership thing. A dog is not just for memes, but admittedly they do make a nice bonus.
