No, you should not. The horse can get caught of something in the pasture or pen, and also if the halter is too tight it can rub bare spots on the horses face, and if left on too long and too tight it the skin can start to grow over the halter. If the horse is hard too catch, you need to practice catching the horse so it wouldn't be a problem, however the halter should not be kept on the horse loose on pasture.
NO!
Training a horse to lead when he has a halter on.
A halter and lead rope. The halter is a device that is strapped onto the horse's head, and then the lead rope can be attached and detached to the halter. The lead rope allows more room between you and your horse while leading for safely reasons.
Don't. If the horse spooks, the lead rope will not come loose. Many horses will then rear when they find that they can't escape. Often, the halter will break, but if not, your horse will be seriously hurt. Always use a slip knot to tie your horse, or if you have to, use a break away halter. Also, never leave your horse alone while tied.
A good strong nylon halter and a lead rope is the safest equipment while working with your horse.
Well, bridles are used for when you are riding. Most have bits, although there is one type called a bosal that uses no bit. Bridles also have reins to hold while riding. You can use a halter like a bridle on a horse, just using the halter and a lead rope, but you cannot attach a bit so it can be very UNSAFE. When riding, you should always use a bridle. Halters are made to lead horses from place to place.
The halter of the horse is used to control them while you are not riding. They are made of cloth (or rope, or leather), and go around the nose, behind the ears, and attach around the throat with a latch. Unlike bridles, there is nothing in the mouth. A halter (also called a head collar) goes around the horses nose, around the back of the head and under the throat. It is used to lead a horse and is made of leather or fabric.
Inhand means you are not physically up riding on the horse. You are showing them off while standing on the ground. A common name for this is halter or showmanship.
Leaving a halter on a horse that is unattended in a stall, pasture or paddock is a REALLY bad and dangerous idea that can have disasterous consequences. Too many horses are injured or die from strangulation because they get the halter caught on a fence post, tree limb, etc. The most common is getting a leg caught in the halter when they use a hoof to scratch an itch. If you feel you must leave a halter on a horse, by all means, make sure you buy the "breakaway" type. If a horse gets the halter snagged on anything, it is designed to break under heavy pressure. Ask your local tack shop. If they don't have it, check around at other tack shops or have them order one for you. It's most ideal if a horse is left unhaltered when unattended. Even with a breakaway halter, they can still be injured. If they're not injured, they will have that emotional trauma of almost being strangled, which can result in some negative behaviors in your horse. *ADDED* Yes, I agree that you should not have a halter on a horse while unattended in a stall or a paddock. If you're going to be going riding, and you have the halter on, make sure you hook the cross ties to his/her halter..If you're outside, and maybe you forgot something, and maybe you're not really--or someone else, may not-- clue in to bring the horse with you--have a friend or family member watch over the horse. But I would recommend he/she holds his/her halter. Many dangerous things can occur all from the same problem - the halter - So, don't leave the halter on...Just bring the halter and lead rope with you. Now, as the person who originally answered this, yes, breakaway halters may be a suggestion to use, but yes, accidents can still happen. Now, I am not sure when you asked this question, but I was also looking for an answer to this, but after knowing it for awhile, I decided to add on to this...but it doesn't have to specifically have to help you, others who are looking for this answer will have something else to read, and will know....
In general, it is expected that you will have your horse's mane and tail braided while showing halter classes. It may not be specifically required, but the judge is likely to mark you down for not doing so.
so that he learns to wait for you to take off his halter, and because it lets them know not to run away while your taking off his halter.
Many people do because their horses are hard to catch, but the best thing to do is train a horse to easily and willingly be caught so you don't have to leave halters on, just to eliminate possible incidents, like while trying to scratch their head with their hoof, mostly with shod horses- the horseshoe catches on the halter easily and can make the horse fall if it gets stuck, and he can seriously injure himself. Or when scratching their head on a tree or fence post, there is a possibility that it could get hung up on a branch or somthing, frightening and possibly injuring the horse. It is made less dangerous with break-away halters, but it's best to not leave a halter on.
