i havent a clue about steroids in coursing dgs but i have heard of fighting dogs being given them and even kids who use these dogs as status symbols will pump their dogs up with roids. it seems probable that some nutter will be using them to enhance their dogs performance in the coursing world.
i only know about the fighting dog thing through heresay but its from people i have no reason to doubt, and i definately dont agree with dog fighting or have anything to do with dog fighting before i upset anyone,
