Although I have a large fenced yard with my three, I don't see the problem with not having a fenced yard. For the first 8 months I didn't have a fence-it just made me work harder to keep my B (Shadow) happy. The biggest thing is to make sure that you can change YOUR thinking. These dogs are not G Shepherds, Boxers, (which I have and a Heeler also) nor are they like any other domesticated dog. You will end up being trained by them. They are not submissive like other dogs and they think independently. You will find yourself putting things away that you never thought possible. Garbage will become a treat to enjoy (whether in the cupboard or not). Shadow has managed to pull the garbage through a small opening where my other dogs couldn't care less. I have baby locks and gates throughout my house and double doors. As has been said many times-please read the stories and then visit and THEN if and only if you can live with destruction, chaos and change and are willing to change your ways of thinking-look for a Basenji! (Sorry to be a party pooper, but we see so many returned, broken, beaten, aggressive and unhappy dogs and people we would rather you see the bad before the good.)
