I am searching to see if gelding him will help stop this agressive behavior?; We got him in September. He was a huge sweetheart when we got him. I have taken him on walks and he was fine. Then he started trying to bite us. When he tries to bite me I tell him firmly NO and I twist his upper lip. We have not started to train him yet, it was winter and all we did was spend time with him, brush him, walk him, etc. The agressive behavior is getting much much MUCH worse. Now when I go out there to brush him and feed him etc. he immediately tries to bite me. And I bet he tries to bite me 10 times every day. He has also reared up and pawed at me as well, two different times. I don't know what to do--we are going to take him to the vet to get him fixed...I was just wondering as this is my first miniature horse if anyone else has had these problems and if getting him fixed will help the behavior, or is it something I am doing wrong and need to do better? What do you guys do if your horse tries to bite you? How do you handle that? Thanks so much for any help you guys can give!
