Gentle Leader

Shaianne is getting an attitude adjustment!!
I just received a Gentle Leader for her. She is not thrilled with it!!!But when I follow the directions with it she does fine.
Does anyone else use one of these and do you have any hints?

(I no longer need to use my gentle leader.)
When I did, and my dog was first getting
use to it, I would carry around treats
in my hand. (I would not allow him to paw at it or rub his nose on the ground)
When he walked nicely I would praise him giving him treats.
Depending on the dog it can take awhile
getting use to it. My female dog with the leader was a pain, but my male, with a little patience and treats got use to it fairly fast.
