Okay, so I have a green horse. I'm training her for jumping with help from my instructor. My horse, Roswitha, truly enjoys it. She perks up and I can feel she gets excited BUT there is one downfall. When the jumps are small, she puts minimal effort into it. We have jumped an OCCASIONAL 2'3" and she clears it perfectly. Small verticals and cross rails, however, aren't spared. Yesterday, I rode her in a small fun show at my barn. Since she's still pretty green we put her in the smallest divisions. First round had ground poles, second had ground poles and tiny cross rails, third round had small cross rails and raised cross rails, and the final division had 18" verticals and a couple cross rails. I trotted the course and she would jump but knock the rails almost everytime. I'd urge her on a few steps before the obstacle but she still would hit them. In the final division, she seriously bulldozed through some of the jumps. She would start lifting her legs but then it was as though she changed her mind and just wanted to run through. She was still perky and uppity but I'm assuming maybe a bit distracted? There have been other times during lessons in which she cleared the higher jumps but would knock over the smaller ones.
Does anyone know a way of fixing this? Or what exercises would help her? Any advice is much appreciated
