Kasianni's idea is really good. A friend here in Australia, up in Sydney, gave a sheltie to an old friend and it escaped the following day. They had to deliver flyers themselves and walked the streets to deliver 2,000 of them, the result being a happy ending. A fellow who had a little farm in between a housing estate and where a 3 lane freeway was being built rang them to say he thought the dog was hiding in blackberry bushes on his farm, and sure enough he was. One of the girls had to do a flying leap to grab him, sheltie's being so ready to bolt, but he was safe after a week of dangerous living on busy streets. I wish you the very best of luck, puphappy, and
that Rio is home soon.
