Why are hot horseshoes put on horses hooves?

People put horse shoes on horses to protect their feet. This coming from a horse back rider, my pony Holly. Thanks.

A:People put horseshoes on horses because most horses are kept in stalls, and in stalls, a horse stands in ammonia from its waste, and this weakens the hooves, so people put horseshoes on their feet as a quick solution so that they dont shatter on roads or other hard ground. However, what many people don't know is that it is actually better for the horse if you do not shoe him. Horses should be left in a pasture and kept barefoot. They can be gradually introduced to hard surfaces and their feet will grow harder like the mustangs. Shoes restrict blood flow through the legs, send harmful vibrations up to the joints and several other things that sacrifices the horses health.
