my sister-in-law just adopted a young dog from the pound and she soon found out he was a barker so she has been using the no bark collar with great success
I think this collar is a great way to stop barking if all else has failed as long as you use it correctly
you only put it on the dog for short intervals if the dog will not stop barking and remove it once the dog has stopped reward for no barking but put collar on if barking.
all my sister inlaw needs to do now is pick up a collar any collar and the dog stops barking right away. he wears a normal collar all the time but he seems to think that when she picks up a collar in her hand it is the no bark one.
useing the no bark collar only took her a week to stop the barking he is a great little man now and only barks if someone comes to the house which is fine with her before he use to just bark for the sake of barking.
good luck
