Pedro, welcome to the forums!! (Do we have a slight language barrier here?:)) I hope you keep posting. I respect the fact that you are asking questions. That's how we all learn–questions, questions, and more questions.
I think what most here are saying is please continue to train and show your pup, but please reconsider any breeding with your dog until all tests are done.
It's a fun trip if you take it..... find sire and dam names. Check in at Sally's site,
http://www.pedigrees.zandebasenjis.com/
follow the links, and you can see the whole lineage picture.
Also (and most importantly) go to the OFFA site… http://www.offa.org/ and see if you can find your pup's sire &/or dam. The information there is not only enlightening, it can be life saving.
BTW…you are correct....There is no 'love' difference between a tested or non-tested dog; they are both loved in the same way, with the same intensity. The love never falters....But.... if you check out all the resources available to you, you can ensure or enable your Basenji to live to a long and loving life with you.
Just my thoughts, Pedro!! Dawn
