I understand 100% what your saying. My dog does this, most recently it was the A Frame in agility. She went up/down it fine, but she was cautious at first. Then she decided that it was fun and literally went up and down that thing over and over. That was about a month ago and every week she does this with the A Frame. She now adds the teeter to it.
