| There is a radio one made by PetSafe. It works very good. No need to put in underground wire or anything. Just a receiver that sits in the house. The the batteries in the collar last about 2 months. We have a Black lab that had the wanders. It cured her of her problem. I think it has a 90' radius which is actually a pretty good sized area. I would recommend this one highly. It didn't take a whole lot of training to break her of her wanderings. | |
