@mvdperez - Not all Basenjis have a freckled belly. I have been in the breed for 25+ years and had a number of Basenjis with no freckled belly. That said in the pictures of her posted you can see the mottled skin under the white hair....
That looks just like the green couch stuffing that i come home to most days (I stopped getting the small tear in the couch sealed after he kept opening the same spot). It's not in a visible location anyways… silly dogs they are 😃
