Ohhh one of these threads where I actually have the horse in question! This is my Appy filly Yukon. She's a sweetheart and absolutely rock-solid calm, sometimes to the point of me thinking she must not have any emotions. Here are some pics of me trying to find things that would unsettle her so we could work on some desensitizing (and failing, even though she'd never seen these things before...) and just one of her outside the barn.
This is her wearing a plastic bag as a nice hat on her ears. She'd never seen a bag before up close so I was SURE this would be the thing... NOPE. Photo 1 (3).jpg
This is her with a stepstool on her back. stepstool.jpg
And of course a regular old saddle. It's monsterous, since it belongs to my half draft, but I figured I'd see how she reacted to it anyways. saddle.jpg
Some bright traffic cones? No problem. traffic cone.jpg
And of course a normal pic of her without me stacking things up on her :) in some grass.jpg
