Training a 3 year old. ?

Wow--there is a lot to digest here--so what I have from these 4paragraphs is you have a 3 year old that has no manners and you want to know where to start? Start at the very beginning and teaching respect. You really cannot move forward doing anything until you have this. That means you will probably butt heads. I got my gelding when he was 2--about the same thing. Not mean, but very spoiled and pushy.. Be.FIRM and CONSISTENT. Make sure that your requests and Ques are clear and precise and the same each and every time. Be firm, not cruel, but make sure he understand that YOU are the boss and he will do as asked or there is a consequence. Break things down very small and work your way up and make sure and praise and praise whenever something is done as you asked for it immediately. Once you have the respect and trust that will be needed--then move forward from there. If you get to a point where you are again butting heads (and you will) break it down again to smaller request-quicker success. What I have found with dealing with different animals is that they all mature totally different paces-just like people do. You can overwhelm a less mature horse VERY QUICKLY (this was my guy-and sounds like your fella too) and you can have to just slow it down and take is in smaller steps. A more mature animal can take things at a much quicker pace. So take your time.
