Has your horse recently started throwing his head with a bit on? When horses throw their head it can be a sign of several things. You should observe your horse to see if he only throws is head with the bit on, or if he throws his head when alone in this pasture or stall. The latter type of head throwing can be neurological or even allergy based and you should stop riding immediately and call your vet.
If your horse only throws his head when the bit is on, there is a good chance the bit, or other element of his tack, is uncomfortable or painful. Headtossing can be related to an improperly fitting saddle, so you’ll want to have your saddle fitted or try riding bareback or with a different saddle. Usually, however, head tossing with a bit on is caused by a bit that does not fit the horse’s mouth, or a bit that is being used improperly.
One of the biggest causes of a horse throwing his head with the bit on is the Tom Thumb bit! Innocuously marketed as a mild snaffle-type western bit, the tom thumb is actually anything but mild and snaffle. When reins attached to a Tom Thumb are pulled, the bit is wrapped around the horse’s jaw like a nutcracker and the joint of the mouthpiece is driven into the roof of the mouth! Sensitive horses can panic and rear when bitted with this bit, but most horses react to the pain of the bit by throwing their head. If you’re using this bit, it’s time to try something else and relegate the Tom Thumb to tack room decor.
If you turn your horse by squeezing a rein in the direct you want to go, try a a plain snaffle like the ones shown here. If your horse turns off cues from your legs and a rein laid against their neck, one of these plain curbs might suit your horse best.
Finally, if a change in bits does not stop your horse from throwing his head with a bit on, consider whether it might be your hands making the horse uncomfortable. One way to test this is to have an experienced friend or a professional trainer ride your horse for a few minutes. If your horse stops throwing his head with a bit on with another rider, you’ll know the horse is reacting to discomfort caused by the way you hold your reins.

If none of these suggestions seem to help your horse stop throwing his head with a bit on, consider whether his teeth may need floated. Horses need regular dental care (called "floating") in order for the bit to fit safely and comfortably in their mouth. Without proper dental care your horses problems throwing their head may becoming increasingly worse, as the pain increases, till the horse is unrideable. Equine dentists regularly float teeth, but most equine vets float teeth as well.
So if you are having a problem with your horse throwing his head with a bit on, try these steps:
1. Observe horse untacked at liberty to see if head throwing is related to tack
2. Check saddle fit
3. Consider the type of bit
4. Consider the way you use your reins
5. Have horse’s teeth examined
A horse throwing his head with a bit on is an annoying and dangerous habit. If you follow these steps you will find and eliminate the cause of your horses head throwing and make your riding time much more pleasant.
