Bark-Free

Probably the best-known of its kind, the Bark-Free system is the desparate neighbor’s solution to barking dogs. It is a box that’s mounted outside as close as you can get to your neighbors’ caterwauling canine, preferably aimed without fences or trees or hedges in the way. It works on the distraction model and claims to be painless but disturbing to the dog. When the dog barks, the device

senses it and emits a tone that is supposed to startle the dog and stop it from barking. Human beings can’t hear the sound. It only has a 25-foot radius, so while it’s fine for the dog next door, the dog across the street may be impervious to its charm. However,you may be able to talk to the other sleepless neighbor across the street and share the cost of the device, then mount it in his yard. You can use it in your own yard, or in your house, with the same caveats stated in the ultra-sonic collar section.
