One negative about being a Pro, you have to develop a sense of detachment for horses you don’t own. Its great to step in if and when asked for (preferably paid) help with horses that are not your own, otherwise, you have to step back. They aren’t yours, owners may not meet your standard of care but they are not in imminent danger and not abused. Let them go.
There are horses in dire need of basics, volunteering time or making donations to legit rescues that are begging for help would be a better use for your free time and energy if you feel the need to give back.
