Okay.. try this.. I have had huge milestones with splash. If you think you know your horse and his issues more then us try this one out because you probably do know him so well and if you do itll work getting him to listen to you.
give the command before he even gets to react he does it so often you said you should be able to anticipate when he's going to do it so give the command to not do it. There all
right what there saying. Trust me and I get what you mean by how do I make him listen just try what I said its the same thing there telling you just in dif. Words. None of us want something wrong with our horses but this is a great place to rant about it and to get info and advice. Let me know if it works for you
