At that time I could groom him loose in his stable, which I will never be able to do again.
With the horse being that young, I have no doubt you'll be able to groom him safely again. You need to find a real
professional to help you though. It sounds like you need quite a bit of help. It seems your colt needs to learn respect and trust. It's good that you sought professional help. I'm sorry that it turned out so negatively for you; however, I would say keep looking for a professional trainer. Before choosing another trainer though, I would ask for references. Past and current clients that you can talk too. Also make sure it is someone who is willing to work with you as well. Good luck!!! And please be-careful!
Oh, and I ditto having him gelded!
