Today I continued with the trust building and repeated all the lessons we have been working on the last few days. He is yielding to pressure a little and I can also lounge him to the left, stop and back to the right.
We had a breakthrough, he allowed me to touch him outside of the shute. He also received his first lesson in being tied with a halter on. It took about 20 minutes but he finally settled in and accepted being tied.
To finish up I was able to lead him around the arena and even take the halter off of him while in the arena.
