Some days, it's just best if I don't respond, but okay.
Please I am begging you, spay/neuter your pets. Contact Brat or Pam Hamilton, firstname.lastname@example.org and get involved with rescue help.
IF your dogs were from good lines, their breeders would be mentoring you. In fact, most good breeders have contracts that forbid you from breeding until you do things like get a championship title, do all health testing including Fanconi DNA, eyes, heart thyroid etc. Have you done those? Many here know lines (I am not a basenji breeder, I just own them and showed one). If you give them your dogs' sire/dam and grandsires/granddams, they may be able to advise you about known health issues etc.
Best idea, truly , is to spay your bitch, help keep her healthy, and share you love of the breed by helping rescue with finding homes for dogs already here.
