The horse I ride, Radar, has done team penning before. He goes into the herd just fine for my coach/trainer (his owner) and was even bred specifically to be cowy. But every time I try to take him in he turns away and balks. Every time. I think it's just because he knows he can get away with it with me. I've tried to spur him (not harshly, but he definitely knows what I think) and crops, but no such luck. I love team penning, and I've done it successfully on a different horse.
Does anyone have any tips please? Maybe your horse or a horse you knew did something similar?
