Some children start dreaming at a young age about owning their own horse. A responsible parent might use a coloring book depending on the age of their child to teach the child what all is involved in the care of a person's horse. Yes, horses are beautiful and they like to run and gallop in pastures, and eat grass, but that is not all that a horse needs to be properly cared for. A parent can use a coloring book to teach a child that the horse needs to be brushed daily and fed actual horse food, not just grass.
