Horses have been central to human transportation and agriculture for centuries. These symbols of power and speed require hoof care and new shoes every four to six weeks to stay on the job. But why?
Horses (Equus caballus) that are domesticated for human use and selectively bred for performance wear shoes because their feet are delicate and therefore need protection, said Dr. Fernanda Camargo, a veterinarian and equine extension agent at the University of Kentucky. "Shoes provide protection to some areas of the foot of the horse," Camargo told Live Science in an email. "They prevent the hooves from wearing out too much, and thus becoming sensitive."
The exterior of the hoof, known as the wall, is made of a horn-like material that grows continuously and has to be trimmed, just like a person's fingernails, according to University of Missouri Extension. "Shoes also help the foot maintain its proper shape," Camargo said.
However, rough terrain, such as sand and rocks, can cause the exterior to wear away, exposing the sensitive inner hoof. Then, the horse experiences pain and may be unable to walk. Historically, such impairments would have prevented horses from being used on the battlefields or during the harvest, so shoes were added to reinforce the hoof wall, Camargo said.
It's estimated that horses have been wearing shoes of some kind since they were domesticated about 6,000 years ago, Camargo said.
Originally, horseshoes were made of leather or plant material. Metal shoes nailed to horses feet were first used around A.D. 500 and became commonplace over the next 500 years, Camargo said. While aluminum and steel shoes nailed to the hoof are still the most common, she said, a variety of other materials — such as rubber, resin and plastic — can also be nailed or glued to the hoof as a shoe.
While many horses need shoes, not all do; it depends on the type of riding, the terrain and how frequently the horse is ridden. Those ridden on rocky terrain or concrete are more likely to need shoes. Even horses that aren't ridden may require shoes to protect them from the terrain or therapeutic shoes to help manage a foot condition. But "a lot of horses that are just ridden here and there, and are kept on grassy/not hard terrain will do just fine without shoes, with regular farrier visits," Camargo said.
Meanwhile, wild mustangs don't wear shoes and manage to travel over rough terrain because they have very strong feet, Camargo said. But their hooves can still wear down and cause lameness. If this happens it will cost a mustang its life, she said.
Some people wonder whether nailing shoes on the horse's hoof hurts them. There are no blood vessels or nerves in the wall of the hoof, according to University of Missouri Extension, so if the shoe is nailed on properly, it isn't painful. "But improper shoeing can absolutely hurt," Camargo said. If the shoes or nails are placed wrong, the shoes are the wrong shape or size, or if the farrier applies pressure in the wrong areas, they can hurt the horse. And if the hooves are badly trimmed beforehand, it can lead to pain or lameness with or without shoes, she said.

Why do horses wear shoes? To get to the other side of the road.Reply
I have seen police horses wearing these rubber shoes. I saw a cop peal one of these off the hoof to clean it, and put it back on. They are shaped like the hoof, and you stretch them and turn them inside out to remove them. To put them back on, you turn them inside out, place them on the hoof, and then turn them back outside out with them now around the hoof. The horses seemed to not mind them at all, and it looked like a real cool way of putting shoes on a horse. No nails, can be removed, and cleaned out, and can be put back on in secondsReply
Horses are shod for three reasons; protection, correction, traction. Horses can work barefoot as long as the hoof is not wearing down faster than it can grow, this is where you need the protection of shoes. Wild horses naturally wear their hooves as they are covering large areas to graze and get water water so they rarely overgrow. Wild horses are not on artificial surfaces like hard roads. There is no demand on the wild Horse to perform with the rider so therefore nature looks after itself.Reply
I have been using the Koio discount code for years and it works great. I am still using it on my work computer and I have no problems with coupons or codes.Reply
Yes, absolutely a great way of caring! But there is still necessary to take care of a horn-like material that grows continuously and has to be trimmed! Otherwise it will break down the rubber shoes!Homer10 said:I have seen police horses wearing these rubber shoes. I saw a cop peal one of these off the hoof to clean it, and put it back on.
