I can see why someone would think there was Terrier, but I'm not so sure about Basenji. (The only way to know for sure is to do a DNA test.) Both of your dogs look very similar. What breed, or mix, is the older one?
@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....
Oh yeah, he looks way more like a b-mix to me than a lot of the pups listed as basenjis on Petfinder. And they mention he's not a barker. What a cutie! Someone go get this guy! 😃
