@Lovelace:
Really? What ones? I don't know of any that have all the criteria? I've done extensive research on the breeds, and i'm curious I don't recall any.
I think Pat means lots of dogs have one or more of these traits. Those three things all together MAY be an indication that the dog does have some basenji in it…but not for sure. Because the dog could be a boxer/husky mix...and end up with right color/markings, pointy ears, a curly tail, and have wrinkle on the forehead (lots of dogs have wrinkles around the face). Rat terriers are notorious for looking like Basenjis...but the shape of their head is slightly different, and the breed was founded using some Basenji way back.
Another thing to remember is that after several generations of mixing, all dogs tend to go back to a natural or pariah dog shape...squarish, brown, pointy ears, slightly curled tail...that is just the natural phenotype of "dog"...so a dog might end up looking Basenji-ish even if there is no actual Basenji there.
I am not refering specifically to the OP...that dog does look like it might have some Basenji in it..or Rat terrier...but it is REALLY hard to say for sure. It doesn't matter really, because everyone is welcome here...Basenji, mix, B-look alike...welcome...
