Using ViceBreaker for problem behaviors is safe & effective and the horse won't even know you're involved. I've been impressed with the ViceBreaker, it allows you to quickly deal with a problem horse's behavior in an effective manner that was not before available. ViceBreaker makes correcting a horse easy, safe and humane.  It's a very useful tool at the farm. I think the ViceBreaker is great to have in the barns to deal with problems early before they become bad habits or vices.  It's a real time & money saver!
