It is important to know the health of the pup and/or their sire/dam
Well said ! It may not seem important now - you can say you will never show or need to register your Basenji - but in a few year's time you may find you wish you had known the health test results of the parents.
By constant checking and careful breeding, many lines have obviated the most devastating scourges, but they are still around.
Better to know for sure if your puppy is tested and imperative to make certain his or her parents were.
