My 45mph friend was spooked by a storm I didn't realize was happening. So I made a crucial mistake, opened the door before the leash was on. A terribly timed lightning flash, and he was gone. He was found by the ID tag on his collar, but lostmydoggie.com spread the word while I searched. A very low probability find happened. Otherwise, I would estimate lostmydoggie.com would have put me a good 2 days ahead of going it on my own.
