I used to have a basenji who would chase a plastic bag I tied to a "wand" around the yard. He seemed really in to the "bunny" so I took him to a couple of lure coursing events in central FL. It was wonderful to see the dogs running and so hard to hold my boy back from joining them. At the end of the day, we were able to do a straight out and back run to see how he would do, and he was great. Not long after, 2 guys that I placed a basenji with rigged up a reversing motor and set up a very small "lure course" in their back yard! There were about 12 of us there with basenjis and we let them chase the bunny one or two at a time. It was great fun. You do have to be careful not to run them too young, or too hard without conditioning.
My current basenji gets to run like crazy at the dog park (it's huge and everyone is very impressed at his speed and agility) and at the baseball field (when it's not locked up).
Slents: I loved your video! Thanks for posting it. I hope you eventually get to attend a lure coursing event in person - it really is something to see!
