Handling by being behind the dog or ahead the dog are both important skills to have. Whichever way you do it, you’ll need to plan the rhythm of your motion as well as your positions: if you want to cross behind your dog, you’ll need to let your dog pass you early enough. On the other hand, if you want to be ahead of your dog, you need to make sure you get to the position you want to be in on the correct time.
