Hello Simba's person. I can tell you love Simba very much, and he is a very beautiful dog. But again, it is hard to know for sure about his genetic soundness, temperament, etc. just from pictures alone, which is why everyone here is going to ask you for his health tests and pedigree. The basenji breeders who speak up on this forum have done a lot to try to improve the overall breed, inside and out, and it is always devastating to hear of haphazard breeding that sets back the efforts of those who are trying to do right by the breed.
I don't know if we can change your mind about breeding your dog here, or at least convince you to do it in a responsible and ethical manner. Please be aware that anyone with a bitch that would be willing to breed to your Simba, at this point, is not someone who has the best interests of the breed in mind. They might see your dog and agree that he is beautiful, but because he has no record of health testing, everybody is taking a risk with the health of the puppies. You might not be doing it for money, but the OTHER person might. Please don't do something that you will regret in the long run, or create misery for a dog that you helped bring into this world.
