I would have the instructor make a short announcement at the beginning of each class that under no circumstance can anyone give your dog (at that point you and the dog step forward and wave )any treats
Before they became "Mini American Shepherds" people would PAL them as Aussies in order to run agility and such.
I know of people who put MACH's on them, then turned around and reregistered them as "Mini American Shepherds" and started over in the novice group. That being a reason I dislike agility (I have my flamesuit on )
Debbie I had an interesting discussion with a well-know local Kelpie trialer who told me there are Great Dane people who are pushing for their dogs to be included in Herding trials. He instinct tested about 5 of them already
I can not picture a Great Dane herding
There is no "holier then though outrage"
It was just a simple question from a person who does not do agility
and was told by local agility people I was crazy for herding in the middle of winter.
reading some of the replies I am now glad I decided against doing serious agility. It would be nearly impossible to run a course in a "Flamesuit"
