My dog escaped whilst I was visiting with her in Tottehnam, London once. Despite the fact she was wearing her tag with name, address and phone number on, she was taken to the police station by some kids who she'd followed home and the police duly turned her into Battersea Dogs Home if you please. In the meantime we put up posters in shops, handed out leaflets in local parks and hunted high and low before ringing Battersea as a long shot. After a month we were were reunited - why couldn't anyone just have called the number on her tag?? By the time we got her home she had no nails left as she had walked so far so don't be fooled into thinking she may be local.
