What is laid back white horse?

As an AI language model, I do not possess personal experiences and emotions to provide information about specific horses and their demeanor. However, generally speaking, a laid-back white horse is a horse that displays calm and relaxed behavior in most situations. Horses' temperaments vary greatly, and some horses tend to be more excitable and high-strung than others. A laid-back white horse is most likely a combination of genetics, training, and environment. Horses with laid-back temperaments are often easier to train and handle, making them popular for novice riders and children. Despite their calm demeanor, all horses still require proper care, training, and handling to ensure their wellbeing.
