Chips are good when someone finds your pet (and takes it somewhere with a chip reader). But many lost pets are scared and skittish and won’t come anywhere close enough to strangers to be caught.

The main purpose of posters is to make people aware.

E.g., a lost dog will usually find an area they feel safe and start hanging around. People near there will see it, and if they know a dog is lost may call it in (getting the number from the poster or social media). Once people looking for the dog know where it is hanging out, they can trap it (maybe first using a drone to narrow down where the dog is).

you say things that are imagined, but in the affirmative. pretty sure I've never seen or heard of drones tracking down dogs although it is a great idea.

Try searching it?

I don’t know why anyone would argue a matter of fact from a position of ignorance, especially when it’s a trivial effort to relieve.
