This is the beginning stages of a drill that I will be using for Dante (10 1/2 month Malinois) to help him understand to always work in straight lines regardless of obstacles or distraction. This exercise has many direct applications into various dog sports where being able to send your dog away from you is essential. However I also find it very helpful for pet dogs as it will inevitably increase your ability to communicate with and control your dog even at distances.
In general, anytime you can increase the clarity of communication between your dog and yourself it will improve your bond, and increase your overall level of obedience.
