Until Europeans brought horses to America, Plains Indians hunted buffalo on foot.
To transport things, they used dogs. That’s why some Plains Indians call the time before Europeans the Dog Days. In the 1500s and 1600s, Spanish soldiers and settlers brought horses to the Southwest. Over the next few hundred years, some horses escaped. They became wild. They multiplied and spread all over the Plains. By the late 1600s, Plains Indians were taming these wild horses. They used them to hunt buffalo. They also traded them. Horses made it easier for Plains Indians to get food, so they created a better life for these people. Some call it their golden age.
