Can youkeep ahorse in a field all year round?

yes you can keep a horse in a field all year round, I do, i reckon it can be healthier for the horse, and yes you can look after it, like grooming in the shelter or tie it to a peice of twine on a post either way is okay, I would personally fence off a small bit of the field for farriers, vets ect. and its always a good idea to have a collection of rugs for a field kept horse.
