Just wanted to update, after a fun day of playing and chasing the lovely lady Claire pup, her owners saw the sign and came and got her! We were happy to see her with her peeps, but sad to see her go.
And it was totally pawsome how we found each other, it turns out Claire had wandered a long ways, more than a mile from where she got lost (her family was visiting someone and she got out...poor thing had no idea where she was). They had papered their area with signs, and we had papered ours with signs, but it wasn't the same area! The lady drove around but didn't quite go far enough south. So there we were just about to take Claire to the vet to see if she had a chip when the phone rang. It was a very nice lady saying, "Hey, I was driving down by Park and I saw a sign that said someone lost a little brown spotted, female dog, then I drove further and saw your sign that you had found a dog that sounds exactly like the one that was lost!" So we got the phone number of the lost dog and Yup it was the same dog.
So here's to all the good folks in the world that help us find our families when we get lost.
