They can, but it's not the best thing for them to wear. They're better off wearing halters made for a cow's head, not a horse's head.
Halters are the most used horse tack! Before you do anything with horses, you should know about it. Halters are how you lead the horse. You use a halter whenever you lead a horse or tie it up. The lead rope attaches to the halter and is what you hold and tie it with.
Halters are used as a type of bridle, almost. When you lead a horse, a halter is used. This allows the leader to have control over the horse without having to wrangle a bridle onto a horse. Most use them when doing ground work with a horse such as lunging and bending. They are simply a control devise when you are on the ground with a horse.
Halters are used for colecting your horse from the fields and stiring around the yard. And bridles are used when riding to stir your horse.
Reins and halters are two things that can be used to restrain horses.
Arabian Horses have especially slender heads, so they canwear regular halters but they may not fit very well.
It is very safe to turn a horse out without a halter. I work at a horse farm, and the only horses we turn out with halters on are those that are VERY hard to catch. Or if the horse has a tendency to escape.
There is no difference between a pony and horse halter. All it is is the size. So, tipically, they are both called halters.
Halters are used to handle your horse on the ground. You attach lead ropes to halters. They do not have bits (the metal part of a bridle that goes in the horse's mouth). When you are riding, a bridle is used. It has a bit that goes in the horse's mouth to help control it. Also, the straps on a bridle are made to control a horse.
What you can make for your breyer horse is tack such as halters,bridles,hoobles. if you are really good at making tack you maybe able to make saddles or rugs/blankets and saddle pads.
It would be the contractors. The bronc riders have to supply their own saddles and girth/flank straps. If they also supplied the halters, then they would control which bucking horse they get, which isn't fair in rodeo competitions. Bronc riders select which horse they ride by pulling a name out of a hat, which is much more fair than them choosing which horse they should or even can ride.
Horse cows do not exist.
cows CAN eat horse pellets, but it is not good for their digestive system. I wouldn't recommend trying it...
