Keep the wind in your favor. That's number 1. Exactly as has been stated in the above mentioned reply's, wait for the right opportunity to draw. In fact I was out hunting last weekend on a club hunt and I know this filed like the back of mmy hand. I usually set up on his escape route and wait for the others to stalk. The wind always give them up before movement. Then being in the right place allowed me to wait for the dog to stop look back, this is when I came to draw and when he looked forward again he made the fatal mistake of trying to sneak out of the field. By this time he was at 20yds, broadside and the rest is part of history. It can be done, but do your homework.If the dog frequents the same area find his den. Monitor the wind at all times and let it fly!
