Yes, I did read the other thread. It's interesting to compare my own observations with those of others. We rented one for a weekend, as an experiment, about two years ago. Gemma would bark, the spray would hit her under the muzzle, she would recoil, and then try again. After a couple of sprays, she stopped barking. The problem was that after a few hours she mastered the art of barking just loudly enough not to activate the sprayer. Although it was weird to hear her barking quietly (only a sheltie cross could pull this one off) we appreciated the decreased volume. We returned the unit to the store with the expectation of buying one in the near future, but we never did.

I think my Scout would do that. She has already figured out to not bark (when I was using a water spray bottle). What she does do however is make alot of noise without actually barking It's amazing the noise that can come out of her mouth w/o barking all the way.
