Years as an Aussie Owner/Trainer Taught Me
Aussies tend to be "ONE Owner Dogs"
If they are bonded to you they will never work well for an out side Trainer.
If they Bond to the Trained they will never be you dog.
Story:
As a Aussie Breeder/Trainer I sold a pup of an age where it bonded well with its new owner.
She brought the dog back to me to train _ on going home they said the dog sulked and was never the Same.
They brought the Dog back, 2 Years Later, when they got to our front gate it bailed out of their Truck and ran our driveway and ended-up in my arms.
I only Trained "Aussie Owners" after that...
