I recently acquired a beautiful 5 yr old mare. She is quite large (15.3). The problem is she is very aggressive toward people she doesn't know that are with me in the pasture. She will come at them with her head down and neck out. She also acts like she wants attention and will follow me anywhere and "nickers" to me but when I get near her she will turn her butt to me and put her ears down. Has never offered to kick or bite ME. But she has no respect for space e.g. she will not get out of your way. I will be breeding her to an extremely gentle stallion soon and he seems to pass this quality on to his foals. *fingers crossed*. I am a greenhorn when it comes to greenbroke (if only in attitude) horses. I think I might be the one who is a little afraid....we need to gain a "trust" for each other. Any advice? I am thinking she was either abused or extremely spoiled with her previous owner(s). I plan on keeping her as I think we can work this out. So any help would be appreciated.
