Teaching dogs how to go around other dogs or bikes or skateboards or...insert whatever they are likely to chase...and come back to you for ANOTHER round of celebration & rewards!
So you have something beside your recall (which if unreliable...) that the dog will understand what TO DO with that herding or chase instinct that got the best of them.
Here's a quick and dirty video of what I took 5 mins to teach them, well less than that...we've got some refining to do, but for now I thought it added some humour to the serious subject.
There are traditional herding cues to use:
"Way to me" is for counter clockwise going around the flock"
"Come bye' or "Go bye" are for clockwise.
I use "go" meaning to move away infront of me and "come" well...that's a recall.... so I thought it would be confusing. For clockwise, I already use "around" for going around poles when on leash so I kept that cue for the clockwise movement.
