After 20 some years of working with horses, my luck has run out. I now have a mare that has a very noticable personality change when it heat.
The weirdest thing that happens is she will lift her feet when I put oil on them. She'll just hold them there all by herself until I'm done putting the oil on and move to the next foot. She's never acted or moved like she was getting ready to let me have it, she just tucks her leg in as far as it'll go.
I know when she's all done being in heat when she just stands there as I put the oil on, LOL
Any one else have weird mares??
