We also have a possible Basenji/Terrier (Yorkie) mix. I've had some doubts, but seeing this picture of Rosie, I can't help but see my Rebel. Such a great looking dog, and if she's anything like our girl, you're in for a treat!
No idea, sometimes with mixes it's so hard to tell what the parentage is. I do think that your dog's head is a bit more refined than many of the pit mixes i've seen.
Hi Chellie-
We had heard that the UC Davis area was very well known for it's vet activities. That said, we're not vets! This was just a way to get a sense of learning what this special dog is, that we've become so attached to. Any answer we get will only make her more special!
