How do I become friends with my horse?

How lovely that you want to build the relationship with your horse. Spending time together matters. Go for walks and do groundwork. Groom him and pay attention to what he seems to enjoy: how he likes to be rugged, brushed and so on. You also get to know your horses by watching how they behave out in the field. Simply being together with no demands can be very effective. Good luck! 🌷
