Just keep on pressing him on until he lowers his head and shows signs or respect and submission
What I do when my horses do that is I run at them a little bit, get in their space. In the wild horses develope dominance by the stallion pushing in on the other.
Okay I will try :) thank you!!
Use two lung ropes put one from the bridle straight too you then another from the other side of the bridle through a roller round his bum then too you I use it on my baby off the track made so much improvement
