Our neighbors dog barked from 6 am until after 8 pm (yes, they were home all the time - both retired). This device "sort of" worked. We turned it to the highest level and aimed it directly into their yard. At least the dog began going to the other side of their yard to bark. Then, my petty neighbors put a concrete block in front of this device to stop the noxious noise only the dog could hear. We refused to sink to their level and would not move the device. They would have just moved the concrete block. Instead, we reported the barking to the homeowners association (which does not allow continual barking). We're sure others complained as well. The barking is not nearly as bad. We're sure it's because they were heavily fined for their continual refusal to stop their dog from barking (money is very near and dear to their hearts). Lesson learned: either conceal this so it can't be seen by your neighbors and be patient (at least the dog will probably move far away from this to continue barking) OR smile and be polite to your neighbors. Then, complain to your homeowners association, requesting they be fined or contact the police. Every town and city has ordinances against "nuisances" such as this. We recommend this as a last resort.....

The concept is great except I had to place it close to the kennel in order for my older dog to react to it properly. Unfortunately one of the dogs got ahold of it and "ate" it the next day. SO if you have an older dog with hearing issues or "stubborn" issues, it's something to think about.

Wow, this thing really works! I was skeptical after my father bought a bark deterrent for his house and it ended up not doing the trick. But this one truly does make dogs stop barking. We just moved into a new house where the neighbors are unfortunately the owners of 2 very excitable dogs. I don't know what breed they are, short medium-sized with a very high pitched bark. They had barked all day and night since we moved in a month ago but there has been nothing but peace and quiet since we put the birdhouse out by the fence. Before we even put it outside my fiance barked like a dog (he speaks dog fluently) and our dog gave the birdhouse a freaked out look, dropped the toy in her mouth, and ran off. I just ordered 2 more, another one for me for the other side of the fence where there are 2 big barking dogs (our yard is much wider than 50 ft) and one for my parents. I am so relieved to have found my blissful silence especially at night when all is quiet now. Sigh!

Started out well and they were afaif of it, then they seemed to get used to it and would still bark

I ordered this item because we like to sleep with the windows open. All night you can hear dogs barking. We purchased the ultrasonic bird house and could not believe it actually worked!! Not only did it stop our dogs from barking but we move it around the fence to stop the neighbors dogs from barking. The only down fall is it does not stop the barking when there are multple dogs, one of our neighbors has 7 dogs. Should have ordered more:)

We have two adorable Jack Russell Terriers living next door to us. Their barking could be quite annoying when it went on for hours at a time and there seemed to be no reason for them to be barking. We installed the "birdhouse" and now Saturday mornings are peacefully quiet as are our dinners on the back porch; and we can still enjoy our playful little neighbors.

I have recommended it to all my friends that own dogs. It has been a blessing. Easy to use and worked after the first bark. Dog walkers in our neighborhood noticed that there dogs did not bark in front of our home anymore. We can now enjoy our quiet home inside and out.

"We purchased the Petsafe Outdoor Ultrasonic Bark Control around April 1. It works like a charm. Not only did it stop our minni schnauzer from barking, it also stopped our neighbors' 3 dogs from barking. Our neighbors were going to purchase the same model because it was so effective, but didn't need to because our unit keeps their dogs quiet also! Didn't have good luck with the indoor model, though. Doesn't deter him as effectively from barking as did the outdoor model."

I use this product at night time and it has worked perfectly. This surpassed my expectations.

"Bought this product out of desperation to have neighbor's dog stop barking. It worked! They no longer leave their dog outside in the front yard, where it would get too excited and never stop barking! I can even move the birdhouse to the backyard on those days when needed! Great product and totally brought down the stress levels for my family."

I read mixed reviews, but took a chance anyway. We were at our wits end with our neighbors complaining and threatening us. The dogs only barked (endlessly!) while we were gone. How do you train a dog when you're gone?? I bought small shock collars and tried it out on myself and immediately returned them. NO WAY!! The very first time we tried this at the lowest setting, we were amazed. So were our neighbors. I knew it was working when we pulled in the driveway after a couple hours of shopping. NOT A PEEP!!! What a weight off our shoulders . We no longer feel guilty about going out. The neighbors are happy and the dogs are perfectly normal, healthy and happy!!!! Great product!! Only drawback is that we have to unplug the phone before we leave, so the ring doesn't trigger the tone.

We read the reviews before we purchased and were very excited to hear how it had worked for others. We have 3 dogs (ranging from 8 lb to 60 lb). Unfortunately, it did not stop our dogs from barking. It stopped their barking the first two days and then did nothing to stop them. We moved it to different parts of the yard but it still did no good.

This product worked great on our own dogs. They stopped barking in just a few days. However, it hasn't helped quiet down our neighbor's dogs, even when less than 15 feet from them. Either they're deaf, or extremely stubborn.

This product worked for me and did exactly what they promised it would! Battery life is phenominal!

Kind of hard to judge whether it works or not. Sometimes it seems to work, other times it does not seem to be effective.
