Such an awesome sport. Too bad it is no longer practiced. Not so here in my home. We don't course by those standards, but, we definately include the dogs on the chase. I use PitBulls. I start training them when they are 6months old. I catch wild game in my live traps, and of course just get the dogs, and the game, up in the field. Then of course we work this out until they are ready for the true test. This is the slingshots to push the squirrel out of the trees, and down on the ground. Then it's the dogs turn. What a super fun time we have. We use the slingshots not to kill but to force the squirrel down to the ground. If you stay with it the squirrel will seek salvation on the ground. The it's on! I have just started my new season, for 2010-2011......The thing to understand is, that you have to use "sight catch instinctive" dogs. American Pitbulls terriers, Patterdale terriers, primarily. They seem to have the best catch instinct......
