I also do want to add that he is mostly Kelpies and having had Kelpies for years they are extremely active and extremely smart. They also need to be able to work independently and think independently, it is what they were bred for.
When they are working well away from their handlers thay are not waiting for commands and signals they have to figure out what to do now, anticipate.
If you think that busy working ability is not in the show Kelpie then let me tell you a little story.
While traveling to Brisbane Royal we stopped to give the dogs a toilet break. We pulled into this property just behind these massive impressive gates, you know the ones that sort of said I'm not a struggling farmer.
The house was no where in sight but because they had good fences we thought it would be a good place to give the dogs a run with no risk of being near the highway. We made a cuppa then turned and saw an entire mob of very expensive looking marino sheep being driven towards us by our RUBISS black kelpie bitch. Well what happened next must have looked like something out of a comedy skit, we threw our cups etc into the boot, called all dogs in, shoved them into the trailer, called Matilda in off the sheep shoved her in the trailer and in a blaze of dust drove out of there so fast for fear that an irate farmer would be after us for running the meat of his sheep or damaging their fine wool. We never took that liberty again.
