I know that unusual is subjective as a breed could be rare in one area but there could be several elsewhere, but I'm just curious to know what the most unusual breed is in your street or area.
Here it's probably a Kerry Blue.
I used to have a Tibetan spaniel so that was probably the most unusual in the last area I lived in, though a neighbour had a Giant Munsterlander and I haven't seem many of those around.
