I have an 18 month old curly-QH cross. He can be the sweetest puppy dog like colt you've ever met but he can also be a little terror. I got him gelded about 6 months ago and I was hoping it would be an easy fix to some of his behaviors but that doesn't seem to be the case. He loves chasing people around the field, running and rearing up at you, biting every once in awhile, and he has started trying to just fall over every time you pick up one of his hooves. I got him at 6 months old and I halter broke him right away and he took to it super fast and he had no problem letting me pick up his feet or lead him around anywhere. Slowly these behaviors have started to pop up along with throwing fits while standing tied and thrashing around/refusing to move when being lead. He's out on pasture 24/7 and if I tried to put him in a stall I feel like he'd taking the whole barn down. I've ever dealt with something like this and I'm at a loss. I love this little guy and like I said he can be the sweetest thing ever but I can't ever be relaxed around him anymore. I don't know how to correct these behaviors and I don't want to wait for them to become worse. Please help!
