I bought this a couple days ago and the first use went very well, it worked as it should and was very effective. However, since then it has gone off several times while walking, squatting to pee and while minimally whining. Maybe the one I got is defective?

I bought this collar for my 4 year old dog, Luna, who has always been highly reactive to other dogs, especially while on leash. We recently adopted a second dog and while walking them, Luna saw another dog, started barking and lunged toward the dog right in front of me, tripping me making me fall face forward onto my other dog and the pavement. I had no choice but to fix this situation and training techniques had not been working. I was skeptical when I bought the PetSafe Audible Bark Collar but was desperate for anything that could help and I did not want to use a shock collar. It immediately startled Luna and made her stop barking and being reactive. It took her a week or so to fully stop barking with it on. Now, even if the collar is turned off, she restrains herself from barking just knowing it might make the spraying noise. Now she is much more manageable on walks. I felt like crying after walking both dogs tonight because we passed two dogs and Luna, with PetSafe collar on, did not make a sound. I use it only while walking her and while she rides in the car and it has been very effective. I do use treat distraction and a harness too. My only complaint about PetSafe is how loud it is when turning it on and off. My dog is startled by beeping sounds so it scares her away whenever I turn it on or off. I wish there was a way to silence this sound. I have just been leaving it turned on 24/7 and the battery is lasting a long time. Overall this product has made our walks much safer, more calm and much more enjoyable. PetSafe is great because it automatically alarms with the spraying sound immediately instead of the owner having to push a button to alert the dog, it is instant. Well done PetSafe, you have really helped me and my dogs! Thank you!

[This review was collected as part of a promotion.] This is a great bark collar, works as it should. I would recommend.

I like that it is rechargeable, saves on battery costs. Just began using the collar, our Chocolate Lab responds to the tone and snaps out of her barking episodes briefly. We are adding in behavior modification routines to reinforce the collar's tone as suggested. Happy with the results so far.
