Dog Rock Records was a DIY label. It managed one single. By Harlow-based Punk band Underdog, 'Life At 12' b/w 'Blue Water White Death', It was issued in 1979, and the sides had their own discrete catalogue numbers - DR-01 and DR-02. The labels were black with white printing and featured what looks like a cartoon bulldog on a lead. Thanks to Robert Lyons For The Info.
