for a Horse
"Horses are by nature social animals. They are herd animals with a need for companionship"
"Horses have an innate ability to get along with a variety of other livestock and farm animals."
"Miniature horses are very chilled out and friendly, and bond with horses of all sizes with ease."
"Goats are friendly, and their sociable nature makes them very likely to bond with horses, happily staying by their side and sharing their hay."
"Llamas make excellent companions for pasture-kept horses, mostly due to their larger size. They can graze in the same spaces and are generally friendly towards horses."
