Petsify [NEWEST 2018] Ultrasonic Anti-Barking Device - State of the Art Bark Controlling Device - Ideal for Dog Training - Safe for Humans and Pets - Unique birdhouse Design - Waterproof

Not sure whether it is working or not. the neighbor dog still barking but not as much.

This device has quieted my cockatoo! However, my lab mix is not enjoying the backyard like she did. I also bought it to quiet the barking dogs in my neighbors yard... this worked as well. I gave it a four and will change to five if my lab mix adjusts!

A lot cheaper looking than I thought it would be. Runs on a 9 volt battery and drains within 2 hours. I'm giving two stars because it does seem to work a little.

Works great to get my dogs to stop barking, the neighbor dogs stopped barking too! Takes a 9V battery (not included) battery runs out fast depending on how long you leave it on.

This product really works! We have three dogs, and one is a 5 month old puppy. The moment I turned the unit on, the barking stopped! There are times when the puppy is excited and sounds off, but after only a few barks she quickly stops and the household is calm. We just moved into a new home, and we were worried about disturbing the neighbors with too much barking, but we are relieved that barking is no longer a concern.Note that this unit uses a 9 volt battery, which is not included. They are easy to find and inexpensive, but I had not been able to find this information on the description pages, so I wanted to include it in the review.

After following directions, the anti-barking house didn't work well. The first time I put it out ,the dog stopped barking, the next time he barked just as much....didn't work that well.

This worked on my dog for about 2 days. Now he just barks through it. Also, people with hearing aids can hear it which is uncomfortable for them.

Update. I moved the unit closer to the neighbor’s yard. Now the dog barks once or twice, stares at the bird house, and is quiet. Happy.I was very hopeful that this would stop my neighbor's dog from barking, but alas it seems I am destined to continue to use earplugs. I have had this hanging in my yard for almost two months, and the dog is unaffected. As information, the 9V battery does last about 4-5 weeks, but be aware that the LED status light blinks VERY brightly, especially at night.
