Yep, and I believe she does have points! And yes, I am 100% sure she's a Welshie.
It occurs in Pembroke Welsh Corgis too - not indicative at all of blindness, since the eye is surrounded by pigment. I had a purebred Pembroke with a blue eye, and she had one of the nicest show/performance pedigrees you'd ever see on a Pembroke.
