What did cowboys really do?

In contrast to the movies, cowboys in real life did not have such crazy lives. They were animal herders, many times not of European descent, that would tend to cattle in North America. They would ride horses and tend to the ranch, and a subtype of cowboy called a wrangler would only tend to the horses that were used to work cattle. A small amount of cowboys also worked at rodeos.

What tools helped them?

The essential tool in their line of work would be the horse. They need the horse so that they could get around faster, carry more tools and have a higher point to look from. There was also a dog present for some but that was not essential. Other essentials are horse equipment such as a saddle and rope for catching cattle. They also wore hats and bandanas to protect from the sun and boots.
