http://www.pet-tales.co.uk/issue6/Shona and I have been quite lucky with our special boys (LuLu & Dave) being runners up in photo competitions on this e-magazine run by Bayer, the Tracer microchip people.
Dave is on page two of this issue by the way
On page six there is a section for you to submit your lost/found stories for the chance to win £100 M&S vouchers
It doesn't specifically say they have to be microchip related but seeing as that's one of their products and that's what the story in this issue was about I think that's what they're looking for!
