Sad as it may be, that adorable little pug puppy your adopted probably never knew its own family. And horses are no different, as we see at the very beginning of War Horse when Joey is taken away from his mother and sold to another farm. But just because these creatures are taken away from their birth family, it doesn't mean they're alone. Joey the horse and Albert the boy practically grow up together, side by side. Their bond is stronger than friendship; it's family. To Albert, Joey's just a brother from another mother—a four-legged one.
