Well I guess I was wrong! Wasn't looking in the right place. I learn new things every day here.
Do you think that they mean it is a rare breed because it is rare to have one that is the breed standard? That has really good blood lines or something?
It's weird because I didn't notice anything like a lab or common breeds like that, and definitely some of the ones listed fall into groups like hound etc.
I'm really curious now. I'd like to get the answer to this one.
