By walking horse I assume you mean the Tennessee Walking horse. I find that my TWH (and many other horses of other breeds) prefer bitless bridles, but bosals aren't good for walking horses because of their head action. The bottom tends to come up and hit them when they move their head, or so I've heard. I ride in a halter, and you can also get the Bitless Bridle.
But other than the bosal, Walking horses will go in anything. If I have to have a bit I prefer a snaffle because it's so gentle, and the horses seem to like it better too.
Bridle training a horse can take a long time. You can start the horse out young however and get them used to it. While the horse is still a foal (If you have the horse while it's that young) get it used to having a leather foal halter on and lead it around gently. As the horse gets older, around a year old or so you can place a bridle (Without the bit) on it's head and begin to lead it with the bridle on. After the horse accepts this you can introduce the bit, a very gentle snaffle type bit is best, give the horse treats while it has the bit and bridle on at the same time. Again once this becomes second nature to the horse to have a bridle and bit on you can begin training the horse to follow the pressure from the bit and how to turn, move forward, and backwards. You'll need a helper for this portion of the training. Eventually the horse will accept the pressure and you will have a horse trained to the bridle.
well its always better to start out with a bit_less bridle .
A bit which is attached to the bridle.
Depends on what type you get
the ansewr is the bridle mounts and the reins
A bit is the part of the bridle that gets put in the horse's mouth. It is usually metal. It's used for control. The reigns are connected to it. A bridle without a bit is built differently to put pressure on different pars of the horse's head to give the rider control with the reigns. Though many riders use bitless bridles for many many reasons, I like them because when my horse and I go on trail rides, we can stop and take a break and I can let my horse eat grass without the hassle of changing from bridle to halter.
It's attached to the reins, the bridle mounts
A bitless bridle is a term that describes a wide variety of headgear for horses that controls the horses without placing a bit in the horse's mouth. A bitless bridle allows the rider to steer the horse more smoothly and reduces pain for the horse.
The bit on the bridle makes it so when the horse tries to graze, it chokes. Also, the horse can step on the reins and trip. Also, if you leave a bit on a horse unsupervised the horse can severely injure itself....including cutting it's tongue off and/or cutting it's mouth open. You should NEVER tie a horse with a bit in it's mouth or leave a horse unattended with a bit in.
A bridle is used to control a horse or pony when you are riding them. Bridles have a "bit" a piece that fits in the horse's mouth and usually a leather strap that fastens behind the jaw of the hourse. When the shanks that are attached to the bit's bridle are pulled by a set of reins that the rider holds, it puts pressure on the horse's jaw and therefore you are able to stop or guide the horse. A bridle is used for a little extra control.If you have a trained horse you will not need to tug and pull a bunch.If you are more experienced you can use your "aids".Your hips,legs and eyes.Your horse can sense shifts of weight.
For horses who have been ridden in a bit less bridle for many years, the best action is to use a gentle, one piece or two piece snaffle bridle. (Do Not use a flash, grackle, or martingale on horses who have not experienced bits before.) Make sure the horse gets used to it before you get on (usually about one week). Make sure your horse can open and close it's mouth, and play with the bit. A good idea is to have "keys" attached to the bit, which encourages the horse to salivate and play with the bit.
Neither a snaffle nor a flash is a bridle. A snaffle is a bit and a flash is a noseband or cavison. A regular cavison is a simple strap the goes around the horse's nose almost half way between the eye and nostril. It buckles under the horse's jaw. A flash is worn lower on the nose and is used to prevent the horse from opening his mouth and 'avoiding' the bit and/or making the bit more effective.
