!4 months is pretty old to not have been weaned!
Certainly by that age, it is not the same as weaning a young foal that still depends on that mare for food.
Treat him just like a buddy sour horse. If he is still a stud, geld him.
Sounds like he was in a situation where it was just easier to leave him with his dam, and not handle him much. Ie, sounds like he came from some backyard breeder, not generalizing all barkyard breeders, but rather what connotation that term is associated with.
Striking, rearing, are all not acceptable, and you must get a handle on this horse, like 'yesterday'
Geld him' separate him, teaching him to accept being parted from his dam, in a safe enclosure
put basics on him,a s you would any other horse that has been allowed to grow up without any manners or respect
I raised foal crops for years, plus bought some 9 month old un handled weanlings. None were allowed to be aggressive towards people, as an excuse for separation anxiety. Good to give him a companion his age, but he must also learn to accept being by himself, or you will just need to 'wean' him off of that comapnion
