@gianna - Note also that most all Basenjis are born in the winter months, it is very rare that there are litters in the spring/summer. Basenjis only come in season once a year and typically all around the same time.
@hawk8875 - Those listing with AKC are paid advertisements. There is no requirement on who can pay to be listed. Go to www.basenji.org and then to find breeder and you can search by state. Breeders listed on there are members of the Basenji Club of America.
Please go to basenji club of america for a list of breeders. If a breeder is not listed there, you can be pretty sure they are not a responsible breeder.

Please do plenty of research before making a decision to have a Basenji.
Where are you in the UK? - if near to me you are welcome to visit my Basenjis and talk Basenji talk. I'm no longer breeding but I think it's important to visit Basenji homes before making decisions. As Benkura says there don't seem to be any female pups available at present. The plus of that is that you've plenty of time to see as many Basenjis as you can. Most breeders are like me and would be pleased for you to visit with their Basenjis.
