Early evening I'm providing fresh linens aka cleaning her stall. As usual Grace is supervising, I of course take breaks to rub on her. I take the soiled linens out via wheelbarrow, again under supervision. Grace is now standing in the barn door, I stop to stand beside her a moment then ask her to move over. My hand is met by not just her muzzle, it's met by teeth!! Not open mouthed, but teeth just the same. My auto pilot has me popping her muzzle accompanied by a loud "Oh No, You Didn't!" She immediately retreated further into the barn, my handy stick was nearby, I invited her to leave the barn (low energy as I'm in there too). Which she did poste haste, I followed her into the pasture with energy. She seemed to "get" that she'd made a huge mistake. I should mention that my hand had been raised when this happened, not in any threatening manner as I'd just had it resting on her neck.
I completed my chores, went out with halter and rope, she came right up to me with no problem. However she wasn't to keen to follow. Once she did she was just fine. Once in the paddock however when asked to move out: her reply was NO, I DONT WANT TO? She did, but I had to demand her to and she objected several times, either by abruptly turning to face me without being asked or attempting to pull away. Even when complying I could feel & see the attitude. I'd stop and reward good behavior with rest, or stop and lead, stop then begin again. Probably 45 minutes, fast running walk her top sped. Finally ended with a long walk in her pasture where I unhaltered her and left.
When I brought her Niall was normal, aside from I didn't allow her to just dig in. She had allow me to own the food, which she did quickly.
Sooooo, could it be 1. she'd felt threatened by my hand? Though her attitude after makes me think, no 2. she's feeling her true self now that she's healthy? 3. she's testing me now that she's healthy? 4. she's a mare? Or 5. any thoughts/input appreciated...
