In my humble opinion this is a pure basenji. Her muzzle looks quite short and this might make you think that she could have Shiba in her but I don't think so.
I find it so hard to see so many basenjis in rescue kennels but I also assume that homes are fairly easy to find. I have just had a case of a Basenji here in a rescue kennel. Usually we try to get them to place them in our specialist Basenji rescue but this dog was quickly homed. Sadly some rescue kennels here are quite anti breeder and won't take any advice from a breeder even if they are not acquainted with the breed. In this case I am trying to persuade them to take my phone number in case the new owner has specific Basenji questions but its taking a lot of persuading!!!!
I do hope these dogs soon get a loving home.
