I have one that we tried with Simon years ago-- he hated it, pawed at it constantly, and it wouldn't stay out of his eyes, no matter how much I adjusted it, so I scrapped using it.
Suzanne Clothier has written a pretty convincing article against using them...but quite a few trainers that I like endorse using them.

I got out our old one and tried it out on Robin today; she took treats ravenously while getting used to it. Any time she wanted to paw at it, I could distract her by walking more, changing direction, or giving her treats.
She definitely didn't shut down. In fact, she went up to our neighbor without barking and jumped on him to get pets.


Just wondered what other people thought about them...
