how about horse ànd pig would they succeed as couple

Not a great combination, I am afraid. The horse likes to run wild and will find the pig's demands difficult. The horse gets restless, the pig likes to stay home. Horses can be skittish and are not always sensitive to the needs and feelings of the pig. Unfortunately, pigs tend to be attracted to the horse. It is best to be friends and keep a careful distance. I would advise against any kind of romance in this combination. The pig should seek for mates among rabbits, goats, dragons, dogs, and perhaps if one is lucky, a particular kind of tiger.
