My next door neighbor uses the birdhouse. We live in a condo and she has a Jack Russel that another neighbor complained about. The birdhouse works like a charm. Whenever he barks it makes a noise that only dogs can hear and they don't like. He doesn't bark hardly at all any-more. One day since then he was barking like a fool. She realized the battery had died and put a new one in. No more barking. It doesn't seem to hurt him at all. He just doesn't like the noise it makes. |
