Agressive horse in round pen!!
I need some advice....my 3 year old horse is disrespectful and aggressive in the round pen when I make him do something he doesn't want to do, like go to the right or left around the round pen. I have done ground work with him....back up, move hip,move shoulders, load in trailer, lead, pick up feet etc. He follows me around the round pen like a puppy and is very laid back and calm. Then when I drive him with my body language and traning stick, he tries to move his hind quarters toward me, runs into the panels, rears, bucks and throws his head and acts like he could charge me. I am only 5'4 and 117 lbs. And don't want to get hurt. I am not afraid to let him know who is boss, but I'm just not sure what the best approach is. I don't want him to get away with disrespect towards me and want to become his strong leader. I'm new at horse training and have read and learned from alot of people, so if you have any resources that you think I would benefit from, I would be more than happy to hear some suggestions.
Please help me, I want to do the right thing with my horse and would greatly appreciate any helpful advice. Thank you!!
