I received a phone call from Roadrunner vet and they said a lady had taken in Halo for shots and a check up. They scanned her and called me! Although the person who found her kept her and posted on craigslist to come and get my dog and that they could not keep her, did not take her to get scanned. I am just happy that the nice lady, who just got her yesterday, took her to a vet and was more than happy to return her to me! It was not so much that they did not utilize yours or any web sites including craigslist, it was that it gave me a peace of mind that you posted and sent the faxes to our local animal control and vets! thank you so much for help in finding my best friend!
