Blu was one of the easiest horses to work barrels on when it came to the pattern and speed. Not so much as the speed adjustment and footing stuff. All I do to train a horse for barrels is:
Figure out which side of the brain the horse uses. If he has better balance or something on the right lead - he's left-brained. Blu has more balance on the left lead. Therefore, he is right-brained and its easier for him to start on the left side. I personally am not comfortable going to the left barrel first and I know its up to me to work on Blu with the right, but I will go to the left if its easier on him. Anyways, I start with walking the barrels a few times to help the horse get the pattern. Then I work at the trot for the most time. Then at the lope. And gradually as the horse learns what he's supposed to do, speed will increase. Tada!
Thank you, thank you. Hold the appalause. Lol. Just kidding.
