set up one pair of 2×2 s to see what Sally thought of them – she saw them and RAN a straight line right past them – looked at me and I must admit I LAUGHED at her. She thought for a second then flung herself through the poles properly and barked at me.
She did it again without the bark and I rewarded her fast.. then she did it again and again. I had to take the poles down to stop her. Her obsessions fascinate me.
