Title: No longer working....
Review: I purchased this product after a woman told me that it works really well. I checked the online reviews and that was the general consensus. I tried it and it worked really well for about a week. Then it suddenly stopped working on my miniature schnauzer. It also has zero effect on my cocker spaniel. I think the schnauzer still hears the sound but it must not be strong enough for her to stop barking.
Is the review positive or negative?
