Humans judge so much by the way things look. Here is my new friend, Minnie, while her ears are not correct for a Jack Russell, I say who the heck cares! Us dogs don't care, the only thing I care about is that she decided I was quite the plaything and was willing to chase and be chased!
Besides how cute can one little dog be! Erect ears and all, she is the cutest JRT puppy I have played with for quite a while. Ears to you Minnie!!
