I am training a horse for a friend for recreation. This horse does not know anything she won't even let me catch her to put a halter on. I have gotten her in to a small pen and tried to get her to warm up to me that way. But she wouldn't give me the time of day. She just paced the pen and got anxious when she couldn't get to her other companions. I mentioned to the owner to let me seperate her from the herd to get her used to being alone. They could not meet that request. This horse seems to be sweet natured, and I know that once I get the halter on her I will be able to catch her and to show her I will not hurt her.
But I can't get close enough to her to put one on. She will get close enough to take a treat from my hand and I can pet her forehead. If I try to get any closer than that she runs off. How can I get this horse to let me get close to her without scaring her?
