Passive income: YES

Starting a pet sitting and dog walking service can eventually lead to passive income, but it largely depends on the scale of the business and the systems put in place. To reach a passive income level, one would need to invest in automation tools for scheduling, billing, and client communication, as well as potentially hiring staff to assist with the workload. While some individuals have successfully achieved passive income in this field through smart business strategies and efficient systems, it is more common for active involvement to be necessary for ongoing success. Setting up such systems can range from $500 to $2000. It typically takes around 2 to 6 months to start seeing profits, with some outliers reaching passive income levels after a year or more.
