This is Kiwi trying to help bring the flock in the other day (at home).
She's not as impressive as the dogs trialing, she still needs a lot of hand-holding to get anything done.
These sheep do not listen to her, you can see them dawdling along and trying to turn around because they do not take her seriously.
She doesn't have the authority Nell had, she isn't as hard as Nell was.
Nell could do this job by herself.
I would send her to gather them and just stand by and wait for the stampede.
The sheep knew not to even bother trying her, they saw her coming and just ran back to the barn immediately.
Maybe someday they'll respect Kiwi the same way, but she needs to build a lot more confidence.
