Dog shows, or "conformation" events concentrate on the distinctive features of purebred dogs and help to preserve these characteristics by providing a forum for evaluating breeding stock.
Dobermans are bred and judged against a blueprint established by the Doberman Pinscher Club of America. This blueprint or breed standard captures the ideal vision for everything the Doberman should be – inside and out.

The Westminster Kennel Club show, held every February, is one of the premiere conformation events in the US. You can relive the 2008 Doberman judging by clicking on this link: http://video.westminsterkennelclub.org/player/?id=216847
