Agreed. It's someone extrapolating out 1 45 minute dog walk @ $X/hr x Y dogs, saying "they work 6 hours per day".

Yeah... perhaps of actual 'walking'. This says nothing about the time required to actually market your business, sign people up, deal with angry customers, not to mention deal with sick dogs, cleaning up crap for multiple dogs daily, and dealing with year-round weather.

If you're in an area where there's enough business to support $100k/year in dog walking, you still can't afford to live well, because that $100k will buy you relatively little.
