@mddebellis, I agree on the sitting with their back to you. Actually, it is possible to put a reliable recall on a Basenji, or at least on some Basenjis, but I would never rely on food because there is always going to be that time when the distraction is more compelling than the food. In my experience they usually want to stay in contact with you and don't stray too far, so in a relatively safe area off leash is doable, but the right distraction could cause them to take off and perhaps go far enough that finding their way back could prove difficult. That said, nothing is foolproof. Leashes break (or are bitten through!), get tugged out of someone's hands, etc. and I do find that a dog that is used to being off leash is safer when the unexpected happens, because they don't get all silly and start playing "keep away". So if possible it's good to give them some off leash experience, and work on a reliable recall, but not everyone has a good place to do that.
