The Clockwise Flank is out to the left. If you and the dog are facing in the same direction and are working together, it’s a working flank.
In dog training terms, the Clockwise Flank is essentially Heel at a distance.
If your dog is moving from left to right in front of you, he is moving clockwise. Turn with him and he will be on the Clockwise Flank.
The Counter Clockwise Flank is like Side position at a distance. The dog is on the handler’s right and is oriented in a counter clockwise direction.
