I have a Bischon/Maltese mix, who is a barker whenever he goes outdoors. I've tried many interventions to little avail. I've used a collar with a remote but I was only able to activate it after my dog barked. If I was fast enough to press the remote it did stop the barking. However, the corrections were very inconsistent as sometimes I was distracted and did not notice that my pup had gone out the doggie door. I purchased this collar and am pleasantly surprised how well it is working to stop nuisance barking. My dog responded to it immediately as he's startled by the beep.I trust he will continue to respond to the correction. I like that the collar is lightweight, so my dog can wear it during the day without any problem. It is sturdy and easy to activate and a real plus is it is rechargeable. I use the beep and vibration and am glad I don't have to use the shock function to quiet my dog.
