It was interesting – right now, I compete very early, and then wait all day, and do all three classes at once. Not fun.
Dulce ran in Novice standard and was not listening. I was ready and had a plan. I stopped, called her to me, ask her to do a few more obstacles, she refused, I excused us from the ring, went to our leash, and she came up and I was able to leash her. Walked her back to the car, put her in her cage, and got Macy as her run was coming up. Made a big deal out of her both before and after her run (she ran clean but over time). Then when it was time to run Dulce, worked on her focus, and went into the ring. She acted up again, I called her, settled her down and started again. This time she did what she was told.
Sometimes punishing a dog works (I removed the opportunity to get rewards for the behaviorists).
