If you belong to Facebook please join the group "Basenji Puppies/Puppys/Puppy’s: Get Educated BEFORE you BUY". You will learn from the group posts and information why the two breeders mentioned above are not considered "reputable" as well as a whole raft of other breeders considered "disreputable". You will also learn what constitutes a reputable breeder. A non-refundable deposit is a red flag, not being able to locate sire and dame test results on OFA is another, contracts where the breeder does not accept full responsibility of their pups or dogs if something goes wrong or you can no longer take care of him/her. Reputable does not mean they have to be a show breeder but usually they are. Not all puppies are meant for the show ring but their breeder should be breeding to the standard as if they were.
