WHO ARE WALKERS? This is a huge question with a great many answers.
Professional Walkers are skilled generalists. As such, they must acquire extensive inter-disciplinary knowledge, training, and in-field skill and experience to work with dogs most successfully. Dogs are sentient beings with biology and behaviour and when those worlds collide, there is much to know and master. The closest comparison is that of canine psychologist and behavioural observer, teacher, guardian, enricher, and hall monitor, rolled into one. The public generally sees the hall monitor and not the more mysterious observation and analyses that precede management tactics.
