I bought a hula hoop recently for a hoop to jump through for a possible trick for Katy to earn her TKN with. She fears it, and goes upstairs to my bed if it is moving around. But it isn't like a startle. For now, i have it laid out on the ground and make sure it is still, and place her meals right in the center of it, to desensitize her. She steps over the edge and into the ring and eats her meal no problem. Going back to one time at the farm store, some metal shelving fell and made a crash(neither of us could see it but we sure heard it), and she ran straight towards the sound, to the end of her leash. No apprehension at all. I have been thinking about these reactions in this way, fear vs. startle. She is better with startle than fear. I'll keep working on that hula hoop tho. Just want her to get to where she can "touch it" even though she feared it the first day she saw it. I do think we will get there.
