Today we working on tying up with this beautifully marked filly. The key is to ask her to step forward into a pressure instead of going with her natural opposition reflex. This sort of training always needs to start with the lead rein threaded through the tie up ring to a human hand rather than tying her up to something she can fight. The lead rein is clipped on to the normal halter ring rather than the training rings of the Dually.
