Speaking of nouns associated with dogs, what is the architectural feature on houses called in which there is an open breezeway between two mostly independent structures? It is a term that has 'dog' in it--and I can't for the life of me remember the term. Dog run? No, I don't think that's it. Isn't a dog run just an area where dogs get their exercise?

wwh, forgive the tangent, please. I, too, have wondered about the size of those dogs that had to pull those dogcarts.
