Though horses don't have sharp teeth, if they bite you it can be very dangerous. Some people have been badly hurt after being bitten by horses. If you are the owner of a horse, or are considering buying one, it is important to understand how to prevent them from biting you or someone else. This is something you want to avoid at all costs.
Biting is a natural behavior for many horses. When horses play together, they often bite, and horses are known for grooming each other with their teeth. When horses are aggressive they will bite and kick in order to demonstrate their dominion over other horses, and this often leads to severe wounds. The owner of a horse needs to make sure the horse understands that they are the person who makes the rules. They should not be biting or nipping any person at all.
Biting and teething are different, and this is important for owners to understand. If you have a horse that likes to bite, their are different things you can do to stop this bad behavior. If it is a foal, firmly rub or massage their nose or lips for about 5 minutes. You want to make sure you don't squeeze. The foal will get tired of the attention, and this is when you will want to stop. The horse will begin holding his nose forward, and will look away from you. This is a good sign. If the horse again approaches with his nose, repeat the same process until they stop.
While many horse owners may find nuzzling to be cute, it can eventually need to nipping and then biting. If you allow your horse to nuzzle it is important to be aware of this. Feeding the horse from your hands often leads to them biting, and if you are currently feeding the horse by hand, you will want to stop this immediately. You should place the treat on the ground instead.
Some horses will make a sharp move towards you when you turn away from them, and this is a bad sign. Any horse that moves toward you quickly with his teeth can bite you. With a horse like this you will want to strike him. You don't want to strike him in the eyes or ears. You don't have to hit them very hard. But you want to make sure that they understand that diving towards you with their teeth is not acceptable.
You don't want to hit them with your hand, as it is too weak to get any point across, and you may hurt your hand as well. A rope is a good tool to use. You want to strike him on the body with enough force that they understand you are disciplining them and not playing with them. While this may sound abusive, there have been cases where people have been badly injured by biting horses, and this is an issue you want to take seriously.
