Here is a great thought Kalley Krickeberg (Parelli Presenter) shared on playing with more than one horse at liberty. It actually relates to everything we do with horses, as well as other animals, and is important to remember!
„… release [reward] on „everybody thinking the same thought“ – this is HARMONY. Harmony is their #1 job, period. One thought, one mind, is natural to them. If you question that, take some time to observe a large herd of horses, wild or domestic. You’ll see it is important to the survival of the herd that all members are on the same page, in harmony, so communication and reaction is rapid and precise.“
