Is My Dog an Appenzeller?

My family adopted a dog from the SPCA. We were told that it was a "Rottweiler mix". One day, I was walking her in a park. A lady came up to us, excitedly. She asked, "Do you know what kind of dog that is?" I said, "uh, a mix from the shelter." She said, "That's an Appenzeller! Look it up."

So I did. Here are some pictures of Appenzellers:
