My filly is 6 months and I tried to get a start on halter breaking, I have always halter broke colts, I did the same thing I do breaking my colts, but she throws a freaking fit. I stop what I am doing and let her finish, because no matter what I do she won't stop until she is finished throwing her fit. I was using a crop but that made it worse. A lot worse. So I tried getting her to make herself tired and she still threw a fit. What can I do?

Also, I have this mare that when I ride her, it looks like she is limping, but her leg isn't hurt, I am going threw equine vet college and I checked out the leg and nothing is wrong. Its just her walking like that. And when I make her go into a trot she bucks and rears and throws a fit UNTIL I smack her with the reins. I hate doing that but I can't risk myself getting hurt. How can I get this to stop? My boyfriend wants to start riding her and I don't want him to get hurt like that. So what can I do to prevent someone getting hurt while riding
