This started Saturday and she hasn’t done it before with me. I am keeping her at an experienced (she has been around horses for a long time and now trains horses) lady’s house with her other horses. I haven’t been able to ask if she does this with her or her husband because they have been out the last two nights when I went by. What she is doing is every time I rub/pet her belly, where the cinch would go, she threatens to bite. She lays her ears back, sticks out her chin and turns her head back towards me. She hasn’t actually bitten or shown any teeth but I still feel like I should correct this. Am I thinking wrong? I have bopped her on the mouth with my elbow (each time she tried I would get more forceful) whenever she does this but that doesn’t seem to help. Would now be a good time to teach her to lunge so I can “drive” her away from me whenever she does this? Or am I going about this all wrong?
She is ok with me rubbing her belly in the cinch area on the left side but not the right and this has not been a problem before. I don’t feel any bumps or anything could she be tender right there?
Some background: I have had Mystic for a little of a month now. She is 6 months old, been wormed, feed grain twice a day, a flake of alfalfa hay a day, and usually there is some prairie hay where she can get some. She is currently in a pen with a mini gelding that is great with her. They feed her in the mornings and I feed her in the afternoon.
She generally will let you pet her anywhere. You can pick up her two front feet and she will let you hold them, I am still working on the back feet (she lets you pick them up but tries to pull away but she is doing better each day with this). She is ok with you running your hand down all of her legs, messing with her ears and face, lifting her tail and with ropes around her legs. She was not messed with any before I got her.
Please don't be too rude but I would like to know your opinon and advice.
