GREAT WORK!
I think it is far more admirable the way your dogs "get it" as i think your way seems to require more brain power than the way i taught Buddy.
cuz we "cheated" by having toybox right under his face, NO WAY could he miss. Buddy got clicked
as toy hit the bottom of toybox, which was
right under his mouth
and THEN we moved toybox just a bit to the side, so we began to have him turn his head slightly to drop toy in,
and THEN we began to have him have to
take a step to drop toy in,
and so on.
Mayyyybe,
if you started with ring-stake right under Jinx's mouth, so when he drops it, it goes on effortlessly, just almost no way to miss hitting the ring-stake at all.......
and then once he has THAT down pat,
then begin to move the stake out a bit to his side, forcing him to begin to turn his head to hit the stake, and so on??? Maybe Jinx is like Buddy, just not a good aim!?
Needing help to "sink the shot" as hardest part of the trick, but CAN'T miss if it is directly under his chin....???
ha ha!!
