Does My Horse Need a Companion?
Look For a Free Companion Horse
A companion horse may be just what you need. Contact a horse rescue, search online horse classifieds, or ask around for a free companion horse. Many people are glad to find good homes for unsound or older horses that can't be ridden for some reason. This will solve two problems; give your horse company and provide a loving home for a horse that may be running out of options. Be aware that you may be getting a horse that needs extra care, so be sure you're able to look after a horse with special needs.
Just because the initial price of a horse is low or zero doesn’t mean its upkeep will be free or cheap.
Go Small
If you don't have the room for an average-sized horse, why not consider a miniature horse? Small but very personable, miniature horses can make excellent companions, with smaller upkeep demands.
Try to Find a Non-equine Friend
A companion for your horse doesn’t necessarily have to be another horse. A goat, donkey, alpaca/llama or some other four-legged creature (like a pot-bellied pig!) could be a buddy for your horse. Some horses are perfectly happy living with other livestock. Others can be a menace; it depends on the species and your horse's personality.
