I have run into a difficulty that I cannot understand. Perhaps somebody could help me out with this. I train my almost 5 year gelding to collect himself in different gaits. We are doing just fine in both raising and sitting trot, as well as in canter – he is nicely carrying himself on the bit with hindquarters engaged and head positioned nicely. But as soon as I ask him to collect while walking, he has started to push out one shoulder and resisting walking straight. I am using leg aids together with neck reining, trying to straighten him out. I begin with light outside leg aid and outside rein against his neck, then stronger, then stronger yet etc, about 5-6 times, until he gives in and straightens out. However, nearly as soon as he straightens out, he pushes out another shoulder and the same thing starts over again, this time to another side. None of this happens while trotting – he nicely carries himself on the bit. Well, he MOSTLY carries himself on the bit while trotting, but even if he tries to “run away”, it is quite easy to get him back on. But not while just walking which, as I supposed, should be easier. He did not do this before, it's a recent behaviour, about a week old. Any idea, what is going on?
