Keep 'Em Wondering
Once widely practiced, flushing on command fell out of vogue in part because of the steady-to-wing-and-shot influence of field trials, but more so because trainers commonly discourage it. When allowed to flush, many dogs assume the command is coming anyway, so why wait? This creates a serious correction problem, but there's a simple way to avoid it. When it's time in the training schedule to teach flushing on command, make up your mind that the dog will not get to flush every time. If you always let him wonder whether this time he gets to go, he won't flush without your say-so.
