Have you heard of how hard it is to have a pet go missing? A community can put up alerts on Facebook and in small towns that can be a quick solution. People in the immediate area will go looking and others will keep an eye out. There are 'animal control officers' who can help facilitate other networks and basically everyone can be supportive and follow a situation along.
Usually in a few days to a week, a dog will be found or return on its own. What a sigh of relief and time of celebration for the owners and friends...and the wider circles on social media.
