So, I have made much progress with Flynn's training so far! He leads with soft hands on the rope, and is desensitized to the rope entirely.
The first time I brought him near a whip , he acted like it was the most normal thing in the world! I
even swung the whip over his head and he flinched a bit, but overall was fine with it.
He finally gave me his front two feet and let us hold them and we can comfortably rub all of his legs from the shoulder and rump, to ankles.
This is all for now!
