Halter breaking is a process of teaching a horse to become accustomed to wearing and being handled while wearing a halter. It's important for the safety of both the horse and handler, as well as forming an important part of groundwork exercises. The best way to start halter breaking is with patience and consistency. Begin by introducing the halter slowly, allowing your horse time to get used to it before trying any further steps. Speak softly and move calmly around your horse when introducing them to the halter; this helps create trust between you two during this sensitive period. Once your horse is comfortable with having their head restrained, you can then begin leading them on short walks in hand or tying them up for short periods at a time (always monitoring). As always remember that every individual has different needs so take care not rush into things too quickly - progress gradually!
