Do you know if his sire and dam were DNA tested for Fanconi? If you did not get any information from the breeder about that, I would highly suggest that you have him DNA tested for Fanconi and PRA. It is a check swab that you do yourself. The results are on an open data base at www.offa.org
Here is the link to order the test https://www.ofa.org/diseases/dna-tested-diseases/fanconi-syndrome and https://www.ofa.org/diseases/dna-tested-diseases/basenji-pra
I would also suggest that you visit www.basenji.org and read up about health concerns for our breed
Now that's a basenji! Are you interested in using him to sire
Did you read that this beautiful dog has unknown pedigree? It would be utterly irresponsible to breed the dog, and shows a distinct lack of knowledge from you. Please, really do give basenjis the "constant love" you posted, learn about responsible breeding.
