Historians have studied the evolution of working-class leisure activities in Britain and debated whether or not they were enduring and resistant to change, pluralistic rather than homogenous, and the extent to which they were subject to continuing attempts at social control. These issues also relate to modern greyhound racing and raise several interlinked questions about the origins and rapid growth of the sport, the social class of its bettors, its cultural development, attempts made to subject it to social control, and the reasons for its decline from late 1940s. The main argument of this chapter is that modern greyhound racing it was essentially a niche working-class activity which was often presented as not being a rational recreation, even criminal, by the forces of anti-gambling, and ultimately fell victim to such discrimination. It did not impoverish the working classes and was, indeed, ‘a bit of a flutter’.
