I am really having some trouble finding a good video of how to harness a mini. Also, how to hook the durn thing to the cart. I have looked on here and on youtube with no luck. I figured out most of it and then just one little movement and the harness I had broke! It was the cheapo indian leather stuff. I thought it would be okay for training, but it isn't functional now after day ONE!!!! Can anyone point me to a good how-to video? I have to find a new harness for him now too.
