Concerns have been raised that Parelli's methods may be "problematic" when used by less experienced horse handlers. What can be learned in a three-day clinic may not be adequate without additional hands-on guideance, especially in difficult circumstances such as adopting a rescue horse that presents additional challenges. Others note that similar difficulties can be expected in any circumstance wherein an inexperienced person is handling a horse without professional supervision. Parelli has commented that it is impossible to learn how to be a natural horseman "overnight" simply by watching his videos.
