I ride Western only. My horses are trained to picket, tie, cross tie, and ground tie. Therefore 95% of the time, unless it's a green or new horse, I unsaddle my horse before I take the bridle off. With that being said, I hardly ever tie a horse after a ride(our rides are 3+ hours normally), so they won't be worked or needed for the rest of the day. They'll stand near us until we are finished, then they all get feed and hay.
Honestly everything is screaming at me to ditch this instructor - especially since she seems to be a little bit bi-polar. A bad, or harsh, instructor can really hurt a child's self esteem!
Sit tall in the saddle, hold your head up high, keep your eyes fixed where the trail meets the sky, & live like you aint afraid to die, & don't be scared, just enjoy your ride.
