This week, Laurie Taylor discusses the phenomenon of weapon dogs with Simon Harding, the author of Unleashed.

Also discussed is the growth of 'Ned' pride in Scotland. 'Ned', or non educated delinquent, is the Scottish equivalent of the English term 'Chav'. It refers stereotypically to uneducated and anti social youth.

But the sociologist, Robert Young, finds that some young Scots, including middle class teenagers, are proudly adopting the 'Ned' label as a mark of sub cultural rebellion.
