The horses are very tolerant of dogs if they don't get aggressive. Our most dominant dog, Lily, was on the same side of the fence and tried to chase them once. It didn't go well for her. She narrowly missed getting kicked then she got chased under the porch. Now she keeps her distance.
The other dogs can walk right up to them and the horses don't care. They know Lily and will lay their ears back and warn her off if she gets too close. They carry a grudge.
watch out for those horses. I once had to reconstruct a dog's jaw after it was broken by a horse which kicked it.
