Re: Catching a moody mare!
Hey, loads of people say that a great way to break the habit is just to catch them, give them a groom or a treat, and then let them go again. If you do this loads of times (and keep your day free so that you don't have to give up) then they should eventually stop expecting a big day out of it. But you have to make it easier for them to be caught than to keep avoiding you.
If you keep 'aggressive/assertive' body language (pressure, direct eye contact, straight posture, wide shoulders and arms etc.) whenever she is doing the wrong thing (i.e. walking away from you), but the second she pays you some attention, looks towards you or stops walking away, then switch to passive body language (stop, drop eye contact, round shoulders and turn slightly away) to give her a break as reward. If she walks away again then switch back, but if she doesn't, try walking up to her, keeping passive. Anytime she walks away from you go assertive, and anytime she makes an effort to do what you want her to (i.e. let you go up to her) go passive and give her a break. If you keep the pattern, it almost always works!
The trick is to catch her, give her a pat and/or a treat, and then let her go again... after a break go back and do it again. You may have to keep the whole day free! The more you do it, the less time it takes each time, until she learns that it's easier to be caught then it is to keep walking way. Its all the same principals as join up basically. But like I said, it also helps to just catch her to spend some quality time together, give her a quick groom, or just a pat once in a while, so that she doesn't always expect work.
Hope any of that helps at all, no worries if not. Best of luck!!!
