It's very simple, as is all training :-). But there are a few things you
have to remember and keep in mind:
back when you want him to let go of something. If you do, he'll just think
it's a fun tug game, and will just pull harder to win it for himself.
the toy to something better (treat, another toy), or continue playing with
the toy for a short while after he has let go of the toy (play starting with
or “take” command).
If you always take the toy away from him when you say “give”, he'll soon
realize it, and won't let go.
So, always make it FUN (change it to something better, or continue playing),
and never chase after him! Otherwise he'll quickly learn that if he doesn't
give it to you, you'll start the fun chasing game. You want your dog to have
a good strong Give command, which will also help with the retrieving
(necessary for waterwork).
Here's how you do it:
Grab the toy with your right hand (remember not to pull!)
Place your left hand (palm down) over your dog's muzzle, so that your
index finder's tip places behind the canines (first red dot), middle
finger next to it. You can use more than two fingers if you need to, but
be careful that they don't get stuck in between the molars (light red
dot). The premolars are smaller and usually there's a little “gap” where
you'll be able to fit the fingers. Your left thumb should go on the
opposite side and point to your index/middle fingers.
With your left hand fingers push the dog's lips between the teeth behind
the canines, and give the command “Give”. Usually the dog will drop the
object almost instantly, though sometimes you'll have to push harder,
depending on how fun the toy is :-). Praise a lot! Give the toy back and
play tug with the dog for a while.
Repeat step 3 a few times (always end with the dog still being excited
After a few sessions, your dog will learn to let go of the toy when you
say so, because he'll associate it to FUN = continuing playing with you.
