I had tried Chadwyk for the first time on the beam with it raised about a foot. He wanted nothing to do with it, so I lowered it to about 4 inches high and used "clicker" techniques to get him to put first one foot, then two then all four and walking across the beam. That last part is what was captured here. He is now 9 months, 28 inches at withers and 68 lbs.
