Mine are 100% on trails......until you "move the furniture". Great on new trails-but on the ones we frequent-if a STICK is moved it becomes snort worthy. So silly. I just laugh and keep going.
I have also found that mine will relax totally if he is following-but put him in the lead and he feels responsible for the world, including me. So, when we are alone he is really vigilant, and, I must say he has kept me safe more than once. So there is a fine line between being silly, and pushing them on, and really paying attention to them.
