I have a mare that's a bluffer. When I saw her at the sale and went up and looked at her with her owner, she was sweet, attentive and so on. When I went back to check on her after I bought her, she was pinning her ears and making the WORST caca face I've ever seen a mare make. Her owner was not there, so I decided insecurity due to new situation. I walked in carefully, she turned her behind to me and got popped with the halter real quick, she went into a corner and sulked. I put the halter on, lead rope and led her out and onto the trailer. I have not seen that caca face since. It's been 10 days since I bought her, she now comes up to me in the pasture, nickers when she sees me and so on. First time she met my husband......here we go....bluffing again. She now loves him too.
Unless their ears are pinned to their necks, and they're giving me snake neck and teeth, I don't pay a lot of heed to mares, they're all about the bluff.
