I remember trying to train Bo Bo on a leash, but that was a no win situation as Bo Bo would not be leashed at all. I put a tie in into the lawn, and had Bo Bo on the other end. I thought Bo Bo would have lots of room to walk around.
Bo Bo diagreed reared back and ran so hard that she broke the leash!!!
It took me a few hours to clam her down , and take the collar off!!!
That was the end of that experiment!!!
