This is a GREAT time for you to get on the forums & get some advice & tips.
I think the number one thing anybody here will tell you is to make sure you are buying from a responsible breeder. Responsible breeders are usually active in conformation (dog shows), or other performance activities (lure coursing, agility, rally, obedience, therapy, etc). They health test (Fanconi, hips, eyes, thyroid) before they breed any of their animals to ensure the puppies will be free of some common, preventable health problems. They have a contract, and they will always take your puppy back if it does not fit in your household for some reason. They will ask to meet you, sometimes more than once, before they allow a puppy to go home with you.
The best thing you can do for your future puppy is make sure it has the best possible start in life… many on here can tell you horror stories about getting basenjis from pet stores, etc.
A responsible breeder will also help you determine if a basenji is the right breed for you. They are very cute, very fun to live with, and very special. However, they have some weird quirks, can be difficult to live with, and are not the right dog for everybody.
Welcome to the forum!!! You will find a LOT of great information here, and lots of friendly, welcoming basenji owners!
