When I feed my three mutts I make them go to their crates while I'm preparing their food (command = taxi to parking).
Then, once I put their bowls on the floor, they are allowed to approach and sit next to the bowls (command = position and hold).
Then they are released to eat (command = cleared for takeoff).
And sometimes I make them "taxi to parking" after they are told to "position and hold." And then we start over.
If I say "line up and wait" they look up at me like I'm stupid. I take that to mean that even dogs know that's a dumb thing to say!
Lesson to be learned, never combine three pretty smart dogs with an overly anal retentive, control freak, pilot. Nothing good can ever come of it.
Okay, back to your regularly scheduled programming!
