If you contact Dog Lost they will advertise the fact that he is missing, put up a poster that you and others can download to put up in the area, give advice on contacting vets. dog wardens, kennels, etc. and advice on what to do if he is sighted - e.g. leaving food out and even arranging for a trap. Have a look at the doglost site and you will be amazed how many dogs are missing. The area is put on, so people in that area can help look and many people give up their time to help search. Also many of us then crosspost the details to dog and other groups we are on, so there is maximum publicity, as this is what brings so many of them home. Their main advice is to poster, poster, poster! so as many people as possible know the dog is missing so if they see it they will recognise it. Poster in chip shops, pet shops, bus stops, pubs (where a lot of stolen dogs get sold on) and on lampposts or noticeboards anywhere you can.
