Front Cross

I was on pinterest and saw this fabulous video for a front cross.  And what is a front cross, you might ask?  As you can see, it is where you cross in front of the dog as the dog runs the course in order for you to change handling sides.  Why do you need to change sides?  It helps you set up a better entry angle or ‘cut off’ your dog from an obstacle you don’t want the dog to take.
