I used to teach dog classes, so I've seen quite a few. Some of the more rare breeds:
Bedlington Terrier (my first dog, plus I had one in class)
Appenzellers (Four of them)
Glen of Imaal Terriers (two)
Mudis (two)
German Pinchers (two)
Chinook (one)
Spanish Water Dog (one)
Kuvasz (one)
American Bulldog (one)
American Water Spaniel (two)
Borzoi (one)
Shiloh sheperd (two)
Leonberger (two)
Tibetan Terrier (two)
Tibetan Spaniel (one)
Of all of them, I really liked the Appenzellers, although they were tough dogs. The Kuvasz and American Bulldog were way too much dog for their owners, and were purchased for looks. Bedlingtons, of course, are close to my heart, but the others didn't dazzle me.
Now to find my Lundehund!
