I've only ever encountered 'Alsatian' in books. As a child I thought it was some British or European breed, but later I realized it's apparently a BE term for what we call a German shepherd. Like Kommissar Rex.
I've never heard of an Alsatian wolf dog, so I would have guessed it was indeed a different (exotic) breed, but Wiki seems to think it too is just a BE alternate name.http://en.wikipedia.org/wiki/German_shepherd#Name
Actually it says that 'Alsatian' was a name introduced around WW1 due to anti-German sentiment, and that it and 'Alsatian wolf dog' are now obsolete, having been dropped from the formal name of the breed in 2010. Since that's so recent, I would guess the old names may be only obsolescent in practice, but some sort of marking seems reasonable. And of course [Brit.].
I doubt that any BE speakers will think to read the discussion under this title, though, so you might have to start a separate thread if you want a survey. Or catch some and send them over if you can. (-:
