I have had my mare for three months now and she has been perfectly fine; but recently she started refusing to walk up to the mounting block. Today, she would randomly refuse to walk on at all, even after I got on, and when I asked her to trot she would put her ears flat back. This behaviour is not like her at all, and shes not in heat and I have had her checked out by several professionals and she doesn't have any pain any where. Any help would be greatly appreciated. I apologize if i have been rude to those people who are kind and giving me suggestions, I was not clear enough at first that I have had her checked for pain, and I doesn't seem to be a factor. I really dont want to be one of those people who wont take advice when they've asked for it. I was also wondering if she has gone barn sour, which would also be strange, and if she has, how I could fix that ??
