YAY!!!!!! Thanks to Ed V. and his connection at the Police Department, I just had Bridget returned to me!!!!!!!!!
The police came to my house and I gave them a flyer and the woman's address, and they went over there and retrieved her for me. She is a couple of pounds fatter (Lord knows what they've been feeding her), she was obviously bathed and brushed, and they trimmed her whiskers (??!!!), but she is doing fine. She was more than ecstatic to see her brother, George. The woman said they found her and had no idea she was someone else's dog (Gee, I guess the collar and tags were not a dead giveaway, you big liar!), but I really don't care, I am just happy she is home again!!!
Thanks again to everyone for your ideas and support--I will definitely look into getting her and George microchipped in the near future.
