Negative Positive
Title: A gamble
Review: I have read reviews from others saying this thing works. However, for my three small dogs it doesn't do much. I know they can hear something because when I push the button to emit the sound I can see them tilting their heads like they hear something. However, it doesn't stop them when they are barking. I am not even sure they can hear it when they are barking. I am wondering if one of the more expensive sound emitting devices would work better.
Is the review positive or negative?
