My brother told me the tale of two elderly people who shared a great old pile somewhere in England. They used to communicate with each other via pug - they would write notes and tuck it in their pugs tightly coiled tail and send him on this way.
I met Dexter outside my house one day. He's about 100 in dog years but I think he would still make a fine messenger.
