The horse has twelve incisors, twelve premolars and twelve molars and may also have extra canine teeth (tushes) and wolf teeth. As the horse has evolved to spend a long time eating fibrous material, their teeth have developed to compensate for constant wear by continually growing. If the diet doesn't contain enough fibre, the teeth are going to grow faster than they are being worn down and hooks are more likely to form either on the outside of the upper molars or inside of the lower molars as they are unopposed by an opposite grinding surface. It is recommended that you get your horses teeth checked by an equine dentist or vet at least once a year. If your horse starts quidding, has choke (bolts his feed or doesn't chew it properly and gets stuck in the throat) or you have biting problems make sure you get your horse's teeth checked.

This term is commonly used to describe the way horses eat little and often. In their natural environment, horses will eat for up to 18 hours a day. Their stomach is relatively small in comparison to their size (stomach of a 500kg horse is about the size of a rugby ball) and the walls do not expand to accommodate a large meal. For these reasons you should not feed more than 2kg of bucket feed at any one time so that you can ensure you are not overloading the digestive system and your horse can maximise what he gets 'out of' his feed.
