When I have a horse that is getting in my space what I do will vary depending on the horse. Some can take the pressure to be more aggressive in what I can do. Others take a less aggressive approach.
I so use a lot of backing. I find that if you can keep their feet moving that it gives them something to do and get them paying attention. Most of the horses I have had that have gotten into my space have been horses who have not been taught to pay attention to the handler. I have had a lot of mares like that come in for breeding. Their owners just let them get away with it and say its b/c the horse is a mare. They are 100 times better by the time they go home. Sometimes it is just the little things you do to.
Like the other day. I was bring Te in through the mares. For some reason he decided to give out a nicker. He knows that is unacceptable. He was disciplined and that was it. All it took was me shaking his halter. I do not normally use a lead rope when I bring the horses in. I either put the lead around their neck or just put a halter on them. Te just had his halter on and I was leading him with just the halter. I gave it a yank and that was the end of it. He knows that if he did not it would go to the next level. Have yet to take it there in years. Once you get their attention and respect and the rules are very clear you rarely will have problems again.
