A few days ago, we were walking in the woods, and crossed some people who were ferreting (put a ferret in a rabbit hole to drive it out and into a net). Voodoo was running off-leash and when we just passed them, a rabbit came out and jumped over the net. We were about 20 meters away from it, and Voodoo immedeately turned around to chase it. He caught it before it could run 30 meter further. The guys with the ferret were quit impressed with that. One of them had 2 lurchers at home, and said my little basenji was maybe even quicker then them. They invited me to come along with them for a few more rabbit holes, to see if Voodoo could catch it again if they were not using nets. So we did. We tried 3 more holes, scared 3 rabbits out of them and Voodoo caught 2 of them before they could escape. The 3rd one managed to dive into another nearby hole. Voodoo killed them all within seconds, only problem was taking the rabbits from him cause I didn't had anything in my pockets to trade them for. We took one home and he got a nice piece of it in the evening. :)
It was a lot of fun and very exiting. So much, that I'm thinking the whole time now of getting a ferret myself and make that our new hobby. He seems really good in it and seems to love doing it (but how could he not love doing some chasing?).
Someone else here who does something simular with their basenji?
