Our 8 year chessie broke out of our fence in fear of the thunder one night, which we didn't realize until late mid day the next day. He did not have a collar or chip. A few days passed and we hadn't heard anything so I signed up for lostmydoggie and Im thankful that the flier got around through social media because it was through the flier that a friend of a friend had our dog and my friend pointed it out that it was our chessie. So thank you Lostmydoggie, you helped reunite our family :) ps now he does have a collar!
