Review Content Works great Bought this as the neighbors dog constantly barks when hes in his yard. Set it up in my garden next to the fence line, and in a few days he had reduced his barking significantly. Glad I purchased it! WONDERFUL GADGET . . . BUT DOES IT WORK? This attractive little birdhouse/bark controller is cute. and after I got it programmed properly, it seems to work well and even runs a long time on one 9-volt battery. The only problem is that my puppy still is barking and the neighbors are still complaining! The instructions say to give it two weeks for your dog to be trained, but its been two weeks now and although I think her barking isnt quite as bad as it was, she still barks almost uncontrollably when the neighbors dog (who doesnt bark) is in their backyard. Im going to keep using the device in the future in the hope that it is eventually effective. In the meantime, it is attractive and fits nicely into my backyard decor, although its a bit pricey for a backyard ornament! Outdoor bark control trainer This product is great. Neighbors dog stopped barking immediately!
