Right you will need to know your horse extreamly well before rushing straight into getting a greater trust, there are many ways in doing this and its important that you think of your horse as your friend not your pet.
Feeding Helps with Bond
My favourite horse named Erin in my stables is a wonderful horse not many peoples favourites but I really do respect her and she respects me. If I am giving her food and I am leaning down at the bucket she will not go near the bucket. This is because the leader always gets to eat first in a horse heard and never shares it unless welcomed too. Once I am away from the bucket that is a sign that I am letting her have the treats.
Clearly Erin respects me by not going in and trying to eat "my" food and as a reward she gets to eat.
Most horses just go into the bucket and push you away. If they do this you must take control and be firm! Even if that doe mean being cruel but fair. Eventually your horse will learn to behave when getting offered food and you will become the leader and you two will respect each other.
Letting a horse eat the food is a sign of friendship. Make sure not to move to far away from the bucket about a metre or two. Also make sure he see's you doing this a make your body launguage welcoming.
Also some horses beg for the bucket of food, if they do beg dont give the food walk away until they settle down and then come back with the food and see if they will behave. ( Some kick their doors, dont let them do this)
Time To Talk
So many people think of there horses as a great pet and the best around, but people have to start treating a horse like they'd treat their friends. Your horse is spose to be your best friend, and best friends have no secrets. Tell him everything! All the things that make you sad and all the moments that make you happy, cry if you want that helps! He has to see that you and him are simlar no matter what!
First talk to him with him munching food once he is finished walk 5 metres ish away from him and keep talking if he runs away then walk away. Make sure not to give any eye contact. Everyday keep doing this until your horse starts to listen to you. Talk to him for about 15 minutes.
Now you have to make it a little more complecated. You will now have to bring the horse food and hold the bucket while he eats it ( Im guessing he doesn't do this ) stand there with no eye contact and dont look at him, try to be still and quite, and wait for him to come to you. This can take over an hour sometimes so be patient and dont give up, that will only make it worse.
Once you have got him eating from a bucket you will then have to be able to do the same but with a bucket with only one treat. See how long he stays with you until he understands there is no more food. Keep doing every day till he knows what is going on and that when hes...he is done!
Once you are sure he is behaving well with this tecnique do the same but once he is finished slowly move your hand into your pocket and put a few more treats in. Keep doing this every day until you see he gets the idea and knows what you're doing.
Now do the exact same as the previous paragraph but once he is done go back into your pockets and put a treat in your hand, hold your hand above the bucket and wait for him to eat, keep doing this until he eats it.
Once you have sucsessfully done that bring the bucket and fill your hands with treats and let the horse eat it from your hands, once he is done give him another treat and then another. Then put the bucket down on the grounf behind you and then give him the treat.
Once he has got the idea come with no bucket and do the same, but hold the food in two hands and use your fingers to stroke his muzzle. Slowly you will be able to move your hand about strocking him near the mouth and he wont be bothered. If you want to extend thi
