The dreaded mistake
You're at an agility trial with your dog. You point to the tunnel, but they go over the jump next to it instead. You're pretty sure you called out the right word, and that your body language was solid, but your dog went to the wrong obstacle anyway.
So what do you do? You go back to the club. You practice a lot with jumps and tunnels next to each other. You drill yourself to ensure you say the right word and move the right way. And everything goes GREAT… until your next trial. This time, your dog goes over the A-frame instead of through the weave poles. Different specifics, but you're off course again.
