I just want to add that Ive only been a horse owner for 3 years, and I have learned alot in this time. I read everything I can get my hands on, watch other people with their horses, learn what I like and dislike by watching trainers on tv/video, and go from there. I, too thought that if you just treated a horse good (fed, cleaned up after them, spent time with them) that would do it. But it doesnt, there are days you just really have to get PO'ed (like the time my ungrateful mare went nuts on me and almost hurt us both) and remember that everything you are doing is in the best interest of your horse or you so that no one gets hurt. For example, I used to watch some horse owners tie their horses to the nearest tree for hours when they wouldnt behave, and Id think to myself, that poor baby tied up to a tree that way. But now, with time and wisdom, sometimes that is the best way to correct a horse that is not minding, it gives you time to think, and them time to realize that bad behavior isnt going to be rewarded and you are in charge. (you keep in mind of course weather etc, I live in texas so its hot) I mean if you have kids, you dont let them get away with bad behavior...and that is really essensially what a horse is, a kid that needs to learn what you expect of them. My gelding tried to kick me one time because he got possesive with his food, so after smacking his butt once and a 30 minute ungrateful piece of ---- lecture, I held his feed bucket for the next week and made him eat with me holding it and messing with him the whole time. He did not like that one bit, but hes never tried to kick me again either. And you will learn in time when they are intentially being difficult and other times you may be giving them mixed signals, but biting is really something that needs to be corrected right away. Honestly its the only time I really smack them in the head area at all (i dont like head shy horses), I immediately pop them on the nose. I did that one time with my mare, and she never tried it again. And young horses will try everything, and thats when they are the most unpredictable. Just keep in mind you are doing it for their best interest.
