I bought her for $50 when she was 7 weeks old from my neighbor(he moved since then). His dog was the dad. I only saw a picture of the dad, he looked jack russell. I never saw the mom. But as she has grown, I have become doubtfull of the info I was given, or what the guy really knew. I love her to death. She is about 12 lbs right now. but only going on 9 months old.
