She has all of the necessities (as I call them), lots of hay, huge stall. But I've always given her treats by hand and grain as well. She got so bad as to chewing a hole in my leather jacket for peppermint patties, granted it wasn't on me, it was on the fence (not sure if that's a o crap my bad or a omgoodness Pepper, you rat!).
She doesn't have terrible ground manners, well sort of, if I ask her to do something like back up, up the gate, bow, voice commands on the lunge line she will do them in a heart beat but when I'm just walking around in the pasture she globs all over me, or gets nasty.
-However at feed time she doesn't, just a hand in front of her bucket and saying no keeps her at bay.
O and another question (SORRY!) Pepper likes to rip down my saddles off the fence when I'm tacking up another horse, she chews the leather or pushes it on the ground, stomps all over it and then is good. Is she being a jerk or would there be a reason for that?
