Echo the above- contact doglost.co.uk. Get them to send you a poster and poster everywhere (shops, minicab offices, vets, petrol stations (the last is v important if you're in a rural area.) Also get in touch with your local traveller liason officer. I usually only lurk on this part of the forum but felt compelled to reply to this as when my godmother's westie got stolen, doglost were fab- we got her back after someone saw a poster on a petrol pump. Also go to local shelters with a photo- they don't always match up dogs right without one.
