Usually I like certain breeds appearance wise because I think they're pretty (not cute), so it was a challenge to think of some I see as cute, but I finally did!
1. Norwegian Buhund
2. Shiba Inu
3. American Eskimo
4. Papillon
^ I probably would never own any of those breeds myself, but I find them to be some of the most adorable to look at.
And I can't think of a fifth breed at the moment... there are individual dogs of all sorts of breeds I find to be cute, but not usually the breed in general. Examples of that would be Dance... Dance is absolutely adorable, but I don't think that of all Tollers. And I think Fransheska's Romeo and Jessie's Tucker are a couple of the cutest dogs ever, but again, I don't think that of all Chihuahuas.
