Trying to get my 3 month old golden to bow (front feet to the ground and
back end up). I started by using the word BOW and she started looking around
the room (last weeks trick was to find the BALL). So I had to pick a
different word, I chose CROUCH.

Starting with the treat in my right hand and, while she is standing, I take
my left hand an put it under her belly. Here is where the trouble starts. If
I use my right hand to drop her front legs, she drops correctly but
instantly gets up, She quickly gets the treat, but she is smelling the treat
the whole time and I don't think she is paying attention. If I swap the
treat hand, I can't get the treat to her quick enough before she stand up.

How is this trick taught?

Thanks
