Mustangs live in the wild all year round. They are extremely tough, resilient horses. If they’re not used to people, they tend to be cautious and reticent when they encounter them. Mustangs are significantly more robust than other horse breeds because they stay outdoors even in cold, wet, and windy weather. In winter, they develop such a thick coat that any snow that lands on it doesn’t melt. In addition to the herd stallion, in every mustang herd, there’s also always a herd mare. She ensures that all the horses in the herd are doing well, and leads them to sources of water or verdant grasslands. If Mustangs are tamed, they are extremely versatile horses that are especially suited to leisure, trail, and endurance riding.
