Can't remember the breeders name offhand but last time she was untraceable, it was my belief that she was more about the money than the dog!
The last home she went to already had a basenji - they knew and loved the breed, reason for return was she would attack their boy basenji and run away when off lead.
Will contact Basenji rescue today although last time were not able to help (if you've a contact name/no would you post save me searching for it)
It is a very difficult situation as i have my own dogs which she has to kept separate from so she will end up spending a lot of time on her own.
Also, most people already have a dog so couldn't take her on….
