You don't! The gag bit is a training aid to improve flexion and collection, that should only be used by an experienced trainer, or under the supervision of a trainer. A gag bit in the wrong hands can be severely painful for the horse, and amounts to torture. IF you have to use torture to get your horse to submit, you need to back up and take stock of your situation. A more severe bit is no substitute for a well trained horse. If you have a horse that bolts, I recommend the use of an experienced trainer. If you can't afford a trainer, replace the horse. There are far too many nice, well trained horses out there for you to justify the risk of riding a dangerous horse. I don't care how much you love it, this horse is not worth your life. I hope you wear a helmet and know how to jump off safely.
A harsh bit is not the solution for a horse that bolts. Proper training is.
beetje beter is the translation in Dutch. It means little bit better.
Stretch them over the rings of the bit.
Yes, Arabian horses that live in Arabia wear bits, the type of bit will vary though, depending on the rider and what is available locally.
A bit is metal bar that is on the bottom of the bridle. This fits inside the horses mouth, behind the teeth, where there is a gap.
Shire horses were not 'discovered', they were created by humans who wanted a bit sturdy draft type horse. The Shire truly began to become a breed in the 16th century when people crossed the Old English Black horse with Dutch horses. The term 'Shire' was used in the mid 17th century to describe the draft horses from the 'Shires' region in England. The breed registry/association opened in 1884 in England.
The bit goes on the bridle, not the halter.
No, the bit goes over the tongue.
A horses bars are the toothless spaces in it's mouth, where the bit is placed.
A snaffle bit is most commonly a jointed bit that works with direct pressure from the reins. There are many different types of snaffle bit, but they are all less severe than a curb bit. A curb bit works in several places on the horse's head, including the poll and roof of the mouth, and is mostly used on strong horses and while driving horses. If a horse has a "soft mouth" (listens to the bit well and does not like pulling on its mouth) and it is not strong or disobedient, then it should have a snaffle. If a horse has a "hard mouth" and is strong or hard to control, it should be ridden in a curb bit, but it is mostly the owner's choice. Some horses go better in snaffles, and some go better in curbs.
