Welcome, Sarah. Hopefully you will find a good responsible breeder in your area, but a healthy, well bred pup is worth a bit of a drive!
Also, have you considered a young adult rescue? There are usually a number of nice, 2-5 year old dogs on BRAT, or Texas Basenji Rescue. If this is your first basenji, I personally recommend starting with an adult! Basenji puppies are really cute…they need to be to keep you from murdering them! A young adult is still very playful, much easier to train, and with life spans of 14-18 years, 2 or 3 is still really young. I won't take a basenji under 2, but I have strong survival instincts.
Good luck on your hunt!
