Barking dogs downstairs
Does anyone know if those devices that emit an inaudible sound to stop dogs barking works for a noisy downstairs apartment. The descriptions only say to put in indoors by the dogs or outdoors on a tree or fence, which in my car is not an option. I wonder if it goes through floors? Anyone know or has used one to stop neighboor's dogs barking. I hear it works great if they are in a yard next to yours. I posted this on another question but then noticed the posting was three years old!
