I am pretty sure you can't just look at a mix and declare what it is. Scientific studies have debunked that over and over. Best to do a DNA test, in my opinion. I have a mix who was advertised as a Basenji Mix, and her DNA results confirmed it. If you just looked at her and made a judgement, it would be mixed: her color was all askew, her tail was half-curled, she was smaller and featured more slender face and feet than a pure-bred B.
But, apparently, the 1/4 Min Pin (the ONLY other DNA in her sample) contributed some significant traits. Behavior and personality wise, Basenji rules the day. Again, I recommend a DNA test, and they improve by the day.
What is this other B identity thing that is mentioned in this thread? Is it also a DNA test, or something else?
Oh, and hey, your baby is way cute!
