I have a three and a half year old gelding that I'm training myself. I purchased him as a yearling, and for the first year and a half, I walked him in hand on the trails around our property. Even without a rider, he always got very antsy about walking downhills, prancing, sidling into the brush at the edge of the trail, etc. I started him under saddle about six months ago, and he's basically doing very well, but he's even worse about going downhill with a rider! As soon as we approach the top of a hill, he starts flaring his nostrils and acting nervous. He does the weirdest things as we head downhill! He tries to turn around and go back, runs into the brush beside the trail, shakes his head, breaks into a trot down the hill, etc. Sometimes he will even stop and back up into the brush and trees along the road as if he's trying to escape it! Has anyone experienced this and if so, have they found a solution, other than just keeping at it. Our trails are very rocky and I realize he may be afraid of slipping, but there isn't anything I can do about them!
