If your horse seems to know the basic rules for behavior but still misbehaves, you may not have a horse who is untrainable, you may have a horse who is questioning your authority.

Respect:

Training your horse is an exercise in trust and respect. If you are working with your horse and you have any feelings that you are fearful or unsure of what you are doing, your horse will pick up on those feelings and quickly lose respect for you. In order to have a well trained horse, he must respect you. If he doesn't respond to your commands, try again and get a mind set for yourself that you are the one in charge and really feel it so your horse will feel it too. He will respect you and cease to question your authority in the horse/owner relationship.

Saddling and Bridling Your Horse:

If your horse doesn't want to suddenly accept the saddle and bridal, make sure neither is causing him pain and then it is easy to reintroduce them. Periodically, you may have to go back and retrain your horse on certain activities. If you don't do them on a regular basis, your horse will push that training to the back of his mind and it may have to be recalled. Let him have a good look and smell at the bridle and saddle again. He will smell himself on them and realize they are okay objects that won't hurt him.

Always treat your horse's fears with compassion and take the time to help him get over them, but do not allow your horse to set the limits. You must always remain in charge of the situation. Never get physically rough with your horse. Always use praise and rewards in your training as it will get you a lot further than harsh treatment. Train regularly and repeat certain lessons frequently as consistency with your horse is the key to all good training!
