I was looking for something to repel my inattentive neighbour's dogs who bark at 5:30 in the morning when they are let out. My bedroom is on the side where the neighbor's kennel is. When the 2 big dogs of the nowhere neighbors bark, the echo between our houses is knocking on our windows. It's so annoying. However, I spoke to them about the barking without caring about my legitimate grievances. Well, now it's all over! I keep a small remote control next to me on my bedside table, and when the baking starts I hit the panic button on the highest level and let the dogs bring it back. Along with the dog bark sound controller I bought it doesn't do much and now it's a small device I feel like I have a little bit more control. If it wasn't for the dogs the rude inattentive neighbors might have been exercised upon hearing the high level alarm!
