i'm not in the ring but my dog has a strong stay.
strangers can call him, offer him treats, pull his leash,
step over him, walk all around with their dogs but he
doesn't move. i taught him stay slowly. first i had him
sit in front. i would say "stay" and take a little step
backwards. the little step became 1 step then 2 steps
and so on. for out of sight stay i would have my dog
sit beside the tire of the car. i say "stay" then i would walk
to the front of the car and duck so he couldn't see me. we did that
for a while. then i woyld hide behind a tree. sometimes i would have him
sit in the yard and i would walk into the house. in the house i would
sit him near a door and i would walk to the other side of the door.
for all of these stays i slowly added in distractions (people calling him,
walking near him with their dogs, etc. in the begining wherever
he was staioned to stay i only did it for a few seconds. the
seconds became minutes and the minutes became 5 minutes,
10 minutes, 15 minutes and so on. when i was doing out of sight stays
i use to sing, bang on things, talk out loud, stump my feet, etc.
i thought being out of sight but making noise would strengthen
start retraining. take it slow. add in the distractions slowly.
if you can set up a ring situation that would be helpfull.
good luck in the ring.
the situations i discussed for teaching my dog to stay
was only a few examples. i set him up in a lot of situations.
