We purchased 2 new horses who have been together for...not even sure how long, but enough that they are spoiled to each other. We let them run with our other horse on 15 acres. We have just started getting them out daily for ground work and lite riding preparing for shows and trails. If we get one out to work and ride, he goes nuts tring to get back to the others. Not to the point of crazy but enough that it isn't alot of fun. Are there any tips on seperation anxiety? Do you think stalling them seperately would help? Anything else? Please help.
