Thanks, the first time trainer for Bonnie was similar:
I'd signed up for the seminar arrived early, got to watch working the other dogs, talked to his assistant/GF who was signing people in, and a young guy who was handling snaked until they chased me off...
There was a lull after me so I got to sit with him and ask some questions...you know the type- on the spectrum smart on dogs, pretty reserved with strangers especially nosy ones like me, but a goldmine once he opened up.
Kind of reminded me of Buck
@Sunje
His partner handling sign-ins was a pro horse rider, barrel racer, done some stunt stuff in hollywood, etc.
The guy grew up around animals- his family had a road side zoo, lizards snakes etc was how he got started...his main gig was falconry: natural management of starlings for farmers...but that was declining so he started snake training, to fill in and it became hos main thing, worked a big circuit.
Here is how it went:
He handled the dogs (not the owners) and would walk a bit, get them calm on leash while another assistant put first snake out on a trail in the sun, obvious to see as come around a cornet....as soon as Bonnie laid eyes on it, indicated interest; took
A step forward: zap.
Wait for her to circle from behind his leg, calm down to a heel sit, walk up again and if she went for it again...zap.
Assistant retrieved the first snake, back to the shady canopy put up the first back in a cooler and opened another pulled out a fresh sevond snake...
Walked out aways out of sight of dog while distracted on heel...this time snake set in long enough grass to conceal, and once clear the dog handler walked Bonnie up on it from downwind...again, easy to see body language tell, and on going for it...zap.
Only once needed.
Repeat the retrieve, replace snake
Last onr was a big angry snake laid out just over a rise behind a log buzzing loudly after being set down.
And trainer walked up same drill.
So it was sight, smell, and sound of the snake with hand of god expert timing on the zap. No commands, other than calm redirext to a heel and walk away get ready again.
This removed the owner who might be slow on the marker.
