I'm pretty sure I've only met 3 rough collies ever.
I've probably met around 2 dozen shibas, though.
Also, I've only ever met one bloodhound, one blue tick, one redbone mix, never a Black and Tan, and only a few foxhound mixes in shelters that got pulled from the south.
I'd say the most popular breeds here besides goldens, labs, and pits are probably cocker spaniels, doodle mixes, frenchies, wheaten terriers...
Then there are always breeds I don't think of as really common but I see tons of and I have to assume there are local breeders, either that or people just get one because they see them around and it builds up - a zillion westies, for example. Bernese mountain dogs. Havanese. I wouldn't be surprised to see these, but I often see 3+ out and about.
I know quite a few Dogue de Bordeaux, too. I know of at least 5 in my area.
